925050fe3f Differentiate between IR_KPTR and IR_KKPTR.
IR_KPTR holds a const pointer to possibly non-const content.
IR_KKPTR holds a const pointer to definitely const content.
Note that only content known by the VM to be const qualifies.
Content tagged as const by users (e.g. const char *) doesn't.

ac76493df1 Specialize bytecode for pairs()/next() iterator. Speedup: 3.5x.
Parser predict pairs/next and emits specialized bytecode.
Bytecode is descpecialized at runtime if the prediction was wrong.
Store slot index in hidden control var to avoid key lookups.

c2c08ba9b3 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.
