Save currently executing lua_State in g->cur_L.
...
This is only a good approximation due to deficiencies in the design of
the Lua/C API. It indicates _some_ valid state that is/was executing.
Also reorder L->cframe stores to achieve a synchronously consistent state.

Record calls to vararg functions.
...
This loop is now roughly 1000x faster than the Lua interpreter:
local function f(a,b,...) end; for i=1,2e8 do f(1,2,i) end
Yet another silly microbenchmark -- I know.

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.
