09ca54d9bc Enable build for x64 interpreter on WIN64. 
To build the x64 interpreter open a "Windows SDK Command Shell".
Then set the compiler environment: setenv /release /x64
Then cd to the src directory and run msvcbuild.bat.

82417ee889 Add build infrastructure for x64 interpreter. 
Must be explicitly enabled with: make clean && make "CC=gcc -m64"
Only works on Linux/x64. Does not work on WIN64 or OSX/x64 (yet).

99d153bef9 Improve alias analysis of upvalues using a disambiguation hash value. 
All upvalue objects hold a disambiguation hash value now.
It's built from the parent prototype and the slot number.
Different hash values imply the upvalues cannot alias.
Same hash values don't imply anything (collision or different closures).
Upvalue disambiguation makes use of a reduced hash due to IR contraints.

93ee10642e Major rewrite of error handling to allow external/internal unwinding. 
Make external unwinding the default on x64.
It's mandatory on WIN64 due to the abundance of callee-saved regs.
Allow piecewise internal frame unwinding and optional cleanup.
Store ERRMEM, ERRERR and ERRCPP early and copy down later.
Use FRAME_CP for lj_vm_resume.
Add lj_vm_unwind_*_eh variants as landing pads for external unwinder.
Use fastcall for lj_vm_unwind_*.
Can drop r12/r13 saves in POSIX/x64 interpreter now.

d18d1573d8 Save all callee-saved x64 integer regs for unwinding.
