  - When it's safe, ActionResult uses the low bit of the pointer for
  the "invalid" flag rather than a separate "bool" value. This keeps
  GCC from generating some truly awful code, for a > 3x speedup in the
  result-passing microbenchmark.
  - When DISABLE_SMART_POINTERS is defined, store an ActionResult
  within ASTOwningResult rather than an ASTOwningPtr. Brings the
  performance benefits of the above to smart pointers with
  DISABLE_SMART_POINTERS defined.

Sadly, these micro-benchmark performance improvements don't seem to
make much of a difference on Cocoa.h right now. However, they're
harmless and might help with future optimizations.

complicated, I've tweaked some logic to make things
conform to how the checking thought things ought to
be, since this results in a simpler "mental model".

Embed the offset of the PTH table inside the prologue of the PTH file.  This will help improve gradual versioning of PTH files instead of relying that the PTH table is at a fixed offset.

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.

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.

This allows us to turn on reconstruction in the pre alloc splitter, which
fixes a number of miscompilations.
