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).

This is the work done by Ryan Brown from http://reviews.llvm.org/D8712 that makes a TypeSystem class and abstracts types to be able to use a type system.
All tests pass on MacOSX and passed on linux the last time this was submitted.

For Hexagon we want to be able to call functions during debugging, however currently lldb only supports this when there is JIT support.
Although emulation using IR interpretation is an alternative, it is currently limited in that it can't make function calls.
In this patch we have extended the IR interpreter so that it can execute a function call on the target using register manipulation.
To do this we need to handle the Call IR instruction, passing arguments to a new thread plan and collecting any return values to pass back into the IR interpreter.
The new thread plan is needed to call an alternative ABI interface of "ABI::PerpareTrivialCall()", allowing more detailed information about arguments and return values.

The new names clarify that the members have to do with the execution
context and not the language. For example, m_cplusplus was renamed to
m_in_cplusplus_method.

expr_options = lldb.SBExpressionOptions()
expr_options.SetPrefix('''
struct Foo {
int a;
int b;
int c;
}

expr_result = frame.EvaluateExpression ("Foo foo = { 1, 2, 3}; foo", expr_options)
This fixed a current issue with ptr_refs, cstr_refs and malloc_info so that they can work. If expressions define their own types and then return expression results that use those types, those types get copied into the target's AST context so they persist and the expression results can be still printed and used in future expressions. Code was added to the expression parser to copy the context in which types are defined if they are used as the expression results. So in the case of types defined by expressions, they get defined in a lldb_expr function and that function and _all_ of its statements get copied. Many types of statements are not supported in this copy (array subscript, lambdas, etc) so this causes expressions to fail as they can't copy the result types. To work around this issue I have added code that allows expressions to specify an expression specific prefix. Then when you evaluate the expression you can pass the "expr_options" and have types that can be correctly copied out into the target. I added this as a way to work around an issue, but I also think it is nice to be allowed to specify an expression prefix that can be reused by many expressions, so this feature is very useful.

that if macros are defined by the modules we don't
try to redefine them. Finally cleaned up a bit of
code while I was in there.

module-loading support for the expression parser.
- It adds support for auto-loading modules referred
to by a compile unit. These references are
currently in the form of empty translation units.
This functionality is gated by the setting
target.auto-import-clang-modules (boolean) = false
- It improves and corrects support for loading
macros from modules, currently by textually
pasting all #defines into the user's expression.
The improvements center around including only those
modules that are relevant to the current context -
hand-loaded modules and the modules that are imported
from the current compile unit.
- It adds an "opt-in" mechanism for all of this
functionality. Modules have to be explicitly
imported (via @import) or auto-loaded (by enabling
the above setting) to enable any of this
functionality.
It also adds support to the compile unit and symbol
file code to deal with empty translation units that
indicate module imports, and plumbs this through to
the CompileUnit interface.
Finally, it makes the following changes to the test
suite:
- It adds a testcase that verifies that modules are
automatically loaded when the appropriate setting
is enabled (lang/objc/modules-auto-import); and
- It modifies lanb/objc/modules-incomplete to test
the case where a module #undefs something that is
#defined in another module.

all the macros from the modules the user has loaded.
These macros are currently imported textually into
the expression's source code, which turns out not to
impose the horrific string processing overhead that
I thought it would, but I still plan to look into
performance improvements.
Also modified TestCModules to test that this works.

A list containing all the arguments to be passed to the expression parser compiler.
This change also ensures quoted arguments are handled appropriately.

the user level. It adds the ability to invent new stepping modes implemented by python classes,
and to view the current thread plan stack and to some extent alter it.
I haven't gotten to documentation or tests yet. But this should not cause any behavior changes
if you don't use it, so its safe to check it in now and work on it incrementally.

This patch creates a HostInfo class, a static class used to answer
basic queries about the host platform. As part of this change,
some functionality is moved from Host to HostInfo, and relevant
fixups are performed in the rest of the codebase.
This is part of a larger effort to isolate more code in the Host
layer into platform-specific groups, to make it easier to make
platform specific changes for a particular Host without breaking
other hosts.
