Summary:
GetDisplayDemangledName will already return a ConstString() when
there is neither a mangled name or a demangled name, so we don't need to special
case here. This will fix GetDisplayName in cases where m_mangled contains
only a demangled name and not a mangled name.

this function requires it to have been initialized.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

also push past code from line 0 immediately following the prologue end.

This is meant to support languages that have a scripting mode with top-level code that acts as global
For now, this flag only controls whether 'frame variable' will attempt to treat globals as locals when within such a function

Create a new "lldb_private::CompilerDeclContext" class that will replace all direct uses of "clang::DeclContext" when used in compiler agnostic code, yet still allow for conversion to clang::DeclContext subclasses by clang specific code. This completes the abstraction of type parsing by removing all "clang::" references from the SymbolFileDWARF. The new "lldb_private::CompilerDeclContext" class abstracts decl contexts found in compiler type systems so they can be used in internal API calls. The TypeSystem is required to support CompilerDeclContexts with new pure virtual functions that start with "DeclContext" in the member function names. Converted all code that used lldb_private::ClangNamespaceDecl over to use the new CompilerDeclContext class and removed the ClangNamespaceDecl.cpp and ClangNamespaceDecl.h files.
Removed direct use of clang APIs from SBType and now use the abstract type systems to correctly explore types.
Bulk renames for things that used to return a ClangASTType which is now CompilerType:
"Type::GetClangFullType()" to "Type::GetFullCompilerType()"
"Type::GetClangLayoutType()" to "Type::GetLayoutCompilerType()"
"Type::GetClangForwardType()" to "Type::GetForwardCompilerType()"
"Value::GetClangType()" to "Value::GetCompilerType()"
"Value::SetClangType (const CompilerType &)" to "Value::SetCompilerType (const CompilerType &)"
"ValueObject::GetClangType ()" to "ValueObject::GetCompilerType()"
many more renames that are similar.

This is more preparation for multiple different kinds of types from different compilers (clang, Pascal, Go, RenderScript, Swift, etc).

debugging optimized code. Adds new methods on Function/SBFunction
to query whether a given function is optimized. Adds a new
function.is-optimized format entity and changes the default
frame-format to append "[opt]" if the function was built with
optimization.
The only indication that a binary was built with optimization
that we have right now is the presence of the DW_AT_APPLE_optimized
attribute (DW_FORM_flag value 1) in the DW_TAG_compile_unit.
The absence of this flag may mean that the compile_unit was not
compiled with optimization, or it may mean that the producer
does not generate this attribute.
Currently this only works for dSYM debugging. When we create
the CompileUnit with dwarf-in-.o-file debugging we don't have
the attribute value yet so it's not set. I need to find the
flag value when we do start to read the .o file DWARF and
set the CompileUnit's status at that point - but haven't
done it yet.
I'm also going to add a mechanism for issuing warnings to users
such that they're only issued once in a debug session and
there is away for users to suppress these warnings altogether
via .lldbinit file settings. But I want to get this changeset
committed now that it's at a useful state.

This API is currently a no-op (in the sense that it has the same behavior as the already existing GetName()), but is meant long-term to provide a best-for-visualization version of the name of a function
It is still not hooked up to the command line 'bt' command, nor to the 'gui' mode, but I do have ideas on how to make that work going forward

This is a purely mechanical change explicitly casting any parameters for printf
style conversion. This cleans up the warnings emitted by gcc 4.8 on Linux.

The many many benefits include:
1 - Input/Output/Error streams are now handled as real streams not a push style input
2 - auto completion in python embedded interpreter
3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use
4 - it is now possible to use curses to drive LLDB (please try the "gui" command)
We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases.

A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error.
This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness.

std::string
Module::GetSpecificationDescription () const;
This returns the module as "/usr/lib/libfoo.dylib" for normal files (calls "std::string FileSpec::GetPath()" on m_file) but it also might include the object name in case the module is for a .o file in a BSD archive ("/usr/lib/libfoo.a(bar.o)"). Cleaned up necessary logging code to use it.

DWARF with .o files now uses 40-60% less memory!
Big fixes include:
- Change line table internal representation to contain "file addresses". Since each line table is owned by a compile unit that is owned by a module, it makes address translation into lldb_private::Address easy to do when needed.
- Removed linked address members/methods from lldb_private::Section and lldb_private::Address
- lldb_private::LineTable can now relink itself using a FileRangeMap to make it easier to re-link line tables in the future
- Added ObjectFile::ClearSymtab() so that we can get rid of the object file symbol tables after we parse them once since they are not needed and kept memory allocated for no reason
- Moved the m_sections_ap (std::auto_ptr to section list) and m_symtab_ap (std::auto_ptr to the lldb_private::Symtab) out of each of the ObjectFile subclasses and put it into lldb_private::ObjectFile.
- Changed how the debug map is parsed and stored to be able to:
- Lazily parse the debug map for each object file
- not require the address map for a .o file until debug information is linked for a .o file

Use the DWARRF end prologue markers when trying to skip prologue instructions instead of blindly using the second line table address entry.

I started work on being able to add symbol files after a debug session
had started with a new "target symfile add" command and quickly ran into
problems with stale Address objects in breakpoint locations that had
lldb_private::Section pointers into modules that had been removed or
replaced. This also let to grabbing stale modules from those sections.
So I needed to thread harded the Address, Section and related objects.
To do this I modified the ModuleChild class to now require a ModuleSP
on initialization so that a weak reference can created. I also changed
all places that were handing out "Section *" to have them hand out SectionSP.
All ObjectFile, SymbolFile and SymbolVendors were inheriting from ModuleChild
so all of the find plug-in, static creation function and constructors now
require ModuleSP references instead of Module *.
Address objects now have weak references to their sections which can
safely go stale when a module gets destructed.
This checkin doesn't complete the "target symfile add" command, but it
does get us a lot clioser to being able to do such things without a high
risk of crashing or memory corruption.
