This is according to my understanding reading the docs, I don't know if it
really agrees fully with what VC++ allows.

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

 - Kill unnecessary #includes in .cpp files. This is an automatic
   sweep so some things removed are actually used, but happen to be
   included by a previous header. I tried to get rid of the obvious
   examples and this was the easiest way to trim the #includes in one
   fell swoop.
 - We now return to regularly scheduled development.

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.

Since that point is now long gone, we should rename LexerToken to
Token, as it is the only kind of token we have.

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.

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.

like this:
t3.c:5:10: error: 'vers2.h' file not found
#include xstr(INCFILE(2).h)
         ^

instead of:

t3.c:5:10: error: file not found
#include xstr(INCFILE(2).h)
         ^

which is useful if the #include name is generated through macro expansion.

of having a loose collection of function pointers.  This also allows clients to
maintain state, and reduces the size of the Preprocessor.h interface.

filenames (and also '#pragma GCC dependency' of course).  Now, assuming
no cleaning is needed, we can go all the way from lexing the filename to
doing filename lookups with no mallocs.  This speeds up user PP time from
0.077 to 0.075s for Cocoa.h (2.6%).

is an intra-lexer property, not a inter-lexer property, so it makes sense
for it to be define here.  It also makes no sense for macros, and allows us
to define it more carefully in the header.

While I'm at it, improve comments and structuring in Lexer.h

that are lexed are made up of tokens, so the calls are just ugly and redundant.

Hook up the MIOpt for the #if case.  PPCExpressions doesn't currently implement
the hook though, so we still don't handle #if !defined(X) with the MIOpt.
