Major 32/64 bit cleanups in assembler and exit handling.

Browse Source 
Add 64 bit lightuserdata handling. Keep the tagged 64 bit value.
Allocate/save/restore 64 bit spill slots for 64 bit lightuserdata.
Fix code generation for 64 bit loads/stores/moves/compares.
Fix code generation for stack pointer adjustments.
Add fixed spill slot definitions for x64. Reduce reserved spill slots.
Disable STRREF + ADD fusion in 64 bit mode (avoid negative 32 bit ofs).
