off_t is a type which is used for file offsets. Even more
specifically, it is only used by a limited number of C APIs that
deal with files. Any usage of off_t where the variable is not
intended to be used with one of these APIs is a bug, by definition.
This patch corrects some easy mis-uses of off_t, generally by
converting them to lldb::offset_t, but sometimes by using other
types such as size_t, when appropriate.
The use of off_t to represent these offsets has worked fine in
practice on linux-y platforms, since we used _FILE_OFFSET_64 to
guarantee that off_t was a uint64. On Windows, however,
_FILE_OFFSET_64 is unrecognized, and off_t will always be 32-bit.
So the usage of off_t on Windows actually leads to legitimate bugs.

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.

(lldb) b puts
(lldb) expr -g -i0 -- (int)puts("hello")
First we will stop at the entry point of the expression before it runs, then we can step over a few times and hit the breakpoint in "puts", then we can continue and finishing stepping and fininsh the expression.
Main features:
- New ObjectFileJIT class that can be easily created for JIT functions
- debug info can now be enabled when parsing expressions
- source for any function that is run throught the JIT is now saved in LLDB process specific temp directory and cleaned up on exit
- "expr -g --" allows you to single step through your expression function with source code

This is a mechanical cleanup of unused functions. In the case where the
functions are referenced (in comment form), I've simply commented out the
functions. A second pass to clean that up is warranted.
The functions which are otherwise unused have been removed. Some of these were
introduced in the initial commit and not in use prior to that point!

What was use_iterator is now user_iterator. Also switch to range-based
APIs, as in Clang r203365.

specify a pointer size until code gen. So we just
make all our pointer-sized integer literals 64-bit.
That doesn't seem to hurt anything.

In almost all cases, the misuse is about "%lu" being used instead of the correct "%zu" (even though these are compatible on 64-bit platforms in practice). There are even a couple of cases where "%ld" (ie., signed int) is used instead of "%zu", and one where "%lu" is used instead of "%" PRIu64.
Fixes bug #17551.

If we are replacing a function with the nobuiltin attribute, it may be called
with the builtin attribute on call sites. Remove any such attributes since it's
illegal to have a builtin call to something other than a nobuiltin function.
This fixes the current buildbot breakage (where LLDB crashes on
"expression new foo(42)").

delete a constant after we replaced it with a
dynamically-computed value. Also ensured that we
replace all users of the constant if there are
multiple ones. Added a testcase.

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.

been suitable for preparing a single IR function
for operation in the target. However, using blocks
and lambdas creates other IR functions that also
need to be processed.
I have audited IRForTarget to make it process
multiple functions. Where IRForTarget would add
new instructions at the beginning of the main
expression function, it now adds them on-demand
in the function where they are needed. This is
enabled by a system of FunctionValueCaches, which
invoke a lambda to create or derive the values as
needed, or report the result of that lambda if it
has already been called for the given function.
