925050fe3f Differentiate between IR_KPTR and IR_KKPTR. 
IR_KPTR holds a const pointer to possibly non-const content.
IR_KKPTR holds a const pointer to definitely const content.
Note that only content known by the VM to be const qualifies.
Content tagged as const by users (e.g. const char *) doesn't.

c93138b59e Major redesign of function call handling. 
Drop call gates. Use function headers, dispatched like bytecodes.
Emit BC_FUNCF/BC_FUNCV bytecode at PC 0 for all Lua functions.
C functions and ASM fast functions get extra bytecodes.
Modify internal calling convention: new base in BASE (formerly in RA).
Can now use better C function wrapper semantics (dynamic on/off).
Prerequisite for call hooks with zero-overhead if disabled.
Prerequisite for compiling recursive calls.
Prerequisite for efficient 32/64 bit prototype guards.

Mike Pall
02e58f5e56 Add support for weak IR references to register allocator. 
Spilling a weak ref forces a spill slot, but omits the restore.
Spill slots for snapshot refs override the register, anyway.
Marking snapshot refs weak avoids pointless restores.

Mike Pall
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.
