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)

enable reuse of MacroArgs objects. This is a small (2.5%) win
on PR5610 (2.185 -> 2.130s). The big issue is that this is making
insanely huge macro argument lists with over a million tokens in it.
The reason that mallco and free are so expensive is that we are
actually going to the kernel to get it, and switching to a bump
pointer allocator won't change this in an interesting way.

remove my hacks that aggressively threw away multiple
instantiation history in an effort to speed up c99-intconst-1.c.
Now that multiple nested instantiations are allowed, we just
make them and don't pay the cost of lookups. With the other
changes that went in before this, reverting this is actually
a speedup for c99-intconst-1.c, speeding it up from 1.96s to 1.80s,
and preserves much better loc info.

This change refactors some of the low-level lexer interfaces a bit.
Token now has a class of kinds for "literals", which include
numeric constants, strings, etc. These tokens can optionally have
a pointer to the start of the token in the lexer buffer. This
makes it faster to get spelling and do other gymnastics, because we
don't have to go through source locations.
This change is performance neutral, but will make other changes
more feasible down the road.

eagerly resolve the spelling locations of macro argument preexpansions.
This reduces fsyntax-only time on c99-intconst-1.c from 2.43s down to
2.01s (20%), reducing the number of fileid lookups from 2529040 linear
and 64771121 binary to 5625902 linear and 4151182 binary.
This knocks getFileID down to only 4.6% of compile time on this testcase.
At this point, malloc/free is over 35% of compile time, primarily allocating
MacroArgs objects and their argument preexpansion vectors.
I don't feel like malloc avoiding right now, so I'm just going to call
this good.

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.
