incorrectly apply the multiple include optimization to files with
guards like:
#if !defined(x) MACRO
where MACRO could expand to different things in different contexts.
Thanks Neil!

both Preprocessor and ASTContext, we no longer need to explicitly pass
MainFileID around in function calls that also pass either Preprocessor or
ASTContext. This resulted in some nice cleanups in the ASTConsumers and the
driver.

Moved all clients of Diagnostics to use FullSourceLoc instead of SourceLocation.
Added many utility methods to FullSourceLoc to provide shorthand for:
FullLoc.getManager().someMethod(FullLoc.getLocation());
instead we have:
FullLoc.someMethod();
Modified TextDiagnostics (and related classes) to use this short-hand.

SourceManager is passed by reference, allowing the SourceManager to be
associated with a specific translation unit, and not the entire execution
of the driver.
Modified all users of Diagnostics to comply with this new interface.
Integrated SourceManager as a member variable of TargetInfo. TargetInfo will
eventually be associated with a single translation unit (just like
SourceManager).
Made the SourceManager reference in ASTContext private. Provided accessor
getSourceManager() for clients to use instead. Modified clients to comply with
new interface.

This removes several gross hacks to work around the previous "lazy" behavior.
Two notes:
- MinimalActions still needs to be taught about the built-in types (This breaks one of the -noop test cases). I started this, then added a FIXME.
- I didn't convert Sema::GetObjcProtoType() yet.

I need to (finally) change the way Class/id/SEL/IMP are built-in...the current approach of doing it in the preprocessor is "broken". The other problem is Sema::GetObjcIdType/GetObjcSelType/GetObjcClassType, the hooks that initialize ASTContext lazily. These built-in types need to be done up front...

predefined macros. Previously, these were handled by the driver,
now they are handled by the preprocessor.
Some fallout of this:
1. Instead of preprocessing two buffers (the predefines, then the
main source file) we now start preprocessing the main source
file and inject the predefines as a "psuedo #include" from the
main source file.
2. #1 allows us to nuke the Lexer::IsMainFile flag and simplify
Preprocessor::isInPrimaryFile.
3. The driver doesn't have to know about standard #defines, the
preprocessor knows, which is nice for people wanting to define
their own drivers.
4. This allows us to put normal tokens in the predefine buffer,
for example a definition for __builtin_va_list that is
target-specific, and a typedef for id in objc.
llvm-svn: 42818
Now instead of IdentifierInfo knowing anything about MacroInfo,
only the preprocessor knows. This makes MacroInfo truly private
to the Lex library (and its direct clients) instead of being
accessed in the Basic library.

it did not handle <xyz> headers coming from macro expansions.
This requires special treatment, as the include name is lexed
as multiple tokens, which require reassembly before processing.

fileid/offset pair, it now contains a bit discriminating between
mapped locations and file locations. This separates the tables for
macros and files in SourceManager, and allows better separation of
concepts in the rest of the compiler. This allows us to have *many*
macro instantiations before running out of 'addressing space'.
This is also more efficient, because testing whether something is a
macro expansion is now a bit test instead of a table lookup (which
also used to require having a srcmgr around, now it doesn't).
This is fully functional, but there are several refinements and
optimizations left.

specifying the start of a token and a logical (phase 3) character number,
returns a sloc representing the input character corresponding to it.

out of the llvm namespace. This makes the clang namespace be a sibling of
llvm instead of being a child.
The good thing about this is that it makes many things unambiguous. The
bad things is that many things in the llvm namespace (notably data structures
like smallvector) now require an llvm:: qualifier. IMO, libsystem and libsupport
should be split out of llvm into their own namespace in the future, which will fix
this issue.
