GDScript: Improve handling of operators
- Use the new functions in Variant to determine the validity and resulting
  type of operators.
- Split the operator function in codegen between binary and unary, since
  the unary ones have now a special requirement of having the second
  argument to be the NIL type when requesting info.

GDScript: Fix mishandling of stack pointers
- Replace the for loop temporaries by locals. They cause conflicts with
  the stack when being popped, while locals are properly handled in the
  scope.
- Change the interface for the codegen so the for loop list doesn't live
  through the whole block if it's a temporary.
- Keep track of the actual amount of local variables in the stack. Using
  the size of the map is misleading in cases where multiple locals have
  the same name (which is allowed when there's no shadowing).
- Added a few debug checks for temporaries, to avoid them being wrongly
  manipulated in the future. They should not live more than a line of
  code.
- Rearrange some of compiler code to make sure the temporaries don't
  live across blocks.

GDScript: Add faster call instructions for builtin methods
Methods from builtin types can be called by using the function pointer
when the argument and base types are known at compile time.

GDScript: Add speficic set/get instructions
When the base type is known at compile-time, we can get a direct
function pointer that is faster than the regular set/get paths.

GDScript: Add faster operator for known types
It now uses the direct operator function pointer, which increases
performance in evaluation.

GDScript: Gather instructions arguments beforehand
Almost all instructions need variant arguments. With this change they
are loaded in an array before each instruction call. This makes the
addressing code be localized to less places, improving compilation
overhead and binary size by a small margin.

This should not affect performance.
