    In practice this is only needed after a return to a lower frame.

    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.

  1. Major redesign of function call handling.

    Mike Pall authored
    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.
