932cda0fe3 Replace on-trace GC frame syncing with interpreter exit.
Need to sync GC objects to stack only during atomic GC phase.
Need to setup a proper frame structure only for calling finalizers.
Force an exit to the interpreter and let it handle the uncommon cases.
Finally solves the "NYI: gcstep sync with frames" issue.

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.

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.

67ca399a30 Compress snapshots using a simple, extensible 1D-compression.
Typically reduces storage overhead for snapshot maps by 60%.

Eliminate IR_FRAME and implement return-to-lower-frame.
