Added opcodes for arithmetic with K operands Added opcodes for all seven arithmetic operators with K operands (that is, operands that are numbers in the array of constants of the function). They cover the cases of constant float operands (e.g., 'x + .0.0', 'x^0.5') and large integer operands (e.g., 'x % 10000').

Towards "to closed" local variables Start of the implementation of "scoped variables" or "to be closed" variables, local variables whose '__close' (or themselves) are called when they go out of scope. This commit implements the syntax, the opcode, and the creation of the corresponding upvalue, but it still does not call the finalizations when the variable goes out of scope (the most important part). Currently, the syntax is 'local scoped name = exp', but that will probably change.

More uniformity in code generation for 'for' loops Added new instruction 'OP_TFORPREP' to prepare a generic for loop. Currently it is equivalent to a jump (but with a format 'iABx', similar to other for-loop preparing instructions), but soon it will be the place to create upvalues for closing loop states.
