c2c08ba9b3 Record calls to vararg functions. 
This loop is now roughly 1000x faster than the Lua interpreter:
  local function f(a,b,...) end; for i=1,2e8 do f(1,2,i) end
Yet another silly microbenchmark -- I know.

96957a4551 Turn some lua_State fields into 32 bit pointers.

4c9f71be5d Major 32/64 bit cleanups in assembler and exit handling. 
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).

67ca399a30 Compress snapshots using a simple, extensible 1D-compression. 
Typically reduces storage overhead for snapshot maps by 60%.
The extensible format is a prerequisite for the next redesign steps:
Eliminate IR_FRAME and implement return-to-lower-frame.
