"logical" location, refer to the "instantiation" location.

Preprocessor: Allocate MacroInfo objects using a BumpPtrAllocator instead using new/delete. This speeds up -Eonly on Cocoa.h using the regular lexer by 1.8% and the PTHLexer by 3%.

Use PreprocessorLexer::getFileID() instead of Lexer::getFileLoc(). This is an intermediate step to having getCurrentLexer() return a PreprocessorLexer* instead of a Lexer*.

Fix the root cause of PR2750 instead of the side effect.
...
NumericLiteral parser is not careful about overrun because
it should never be possible. It implicitly expects that its
input matched the regex for pp-constant. Because of this, it
knows it can't be pointing to a prefix of something that
looks like a number. This is all fine, except that __LINE__
does not prevent implicit concatenation from happening. Fix
__LINE__ to not do this.

__VA_ARGS__ syntax as well as with the amazingly awesome GNU "named
variadic macro" extension. Allow it with the GNU syntax as well.

Make a major restructuring of the clang tree: introduce a top-level
...
lib dir and move all the libraries into it. This follows the main
llvm tree, and allows the libraries to be built in parallel. The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in. This speeds
up parallel builds, particularly incremental ones.
