c225ee8db4 Split CALL/FUNC recording.
Record __call resolving and specialization for CALL* bytecodes.
Record argument adjustment and fast functions for FUNC* bytecodes.
Avoids all pending/immediate decisions for chained fast functions.
Cleaner semantics for pcall(), xpcall() and __tostring metamethod.
Prerequisite to drop the shadow frame link stack again.

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.
