Register promotion fix

Restructured the type inference mechanism, added lots of DCHECKS,
bumped the default memory allocation size to reflect AOT
compilation and tweaked the bit vector manipulation routines
to be better at handling large sparse vectors (something the old
trace JIT didn't encounter enough to care).

With this CL, optimization is back on by default.  Should also see
a significant boost in compilation speed (~2x better for boot.oat).
