659ea9de7b Ensure function and all args have a reference for call recording.
In practice this is only needed after a return to a lower frame.

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.

7256690364 Add shadow frame link stack for trace recorder.

Increases consistency for fast function calls, too.

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.

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.
