Make the Preprocessor more memory efficient and improve macro instantiation diagnostics.
When a macro instantiation occurs, reserve a SLocEntry chunk with length the
full length of the macro definition source. Set the spelling location of this chunk
to point to the start of the macro definition and any tokens that are lexed directly
from the macro definition will get a location from this chunk with the appropriate offset.
For any tokens that come from argument expansion, '##' paste operator, etc. have their
instantiation location point at the appropriate place in the instantiated macro definition
(the argument identifier and the '##' token respectively).
This improves macro instantiation diagnostics:
Before:
t.c:5:9: error: invalid operands to binary expression ('struct S' and 'int')
int y = M(/);
^~~~
t.c:5:11: note: instantiated from:
int y = M(/);
^
After:
t.c:5:9: error: invalid operands to binary expression ('struct S' and 'int')
int y = M(/);
^~~~
t.c:3:20: note: instantiated from:
\#define M(op) (foo op 3);
~~~ ^ ~
t.c:5:11: note: instantiated from:
int y = M(/);
^
The memory savings for a candidate boost library that abuses the preprocessor are:
- 32% less SLocEntries (37M -> 25M)
- 30% reduction in PCH file size (900M -> 635M)
- 50% reduction in memory usage for the SLocEntry table (1.6G -> 800M)

The PreExpArgTokens array is indexed with an argument #,
not a token number. Fix the reserve logic to get the right
amount of space.

set up the machinery for a MacroArgs cache hanging off Preprocessor.
We creating and free thousands of MacroArgs objects (and the related
std::vectors hanging off them) for the testcase in PR5610 even though
there are only ~20 live at a time. This doesn't actually use the
cache yet.

move the VarargsElided member of MacrosArgs to shrink the MacroArgs struct
on 64-bit targets. Pass Preprocessor into create/destroy methods of MacroArgs
even though it isn't used yet.

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.
