TODO
====
- check use of float NEGOP vs NEGFAC for cx16
- allow inlining of subroutines with params
- optimize several inner loops in gfx2
- hoist all variable declarations up to the subroutine scope *before* even the constant folding takes place (to avoid undefined symbol errors when referring to a variable from another nested scope in the subroutine)
