Some micro-optimizations for DISABLE_SMART_POINTERS:
- 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.
