Constant fold all kinds of constants

This patch exports all the binary operator builtins functions from builtin.c and uses them for constant folding in the parser, allowing constant folding to work will all kinds and combinations of constants.

Now string*number, $ARGS+$ARGS, string/string, etc will also be constant folded and the implementation of constant folded operators and runtime operators will be the same.

And thanks to the new ERRORK bytecode operation, errors are constant folded too! (e.g. 1 / 0 [] * {} etc)
