TODO
====
don't write pointer types into P8IR files, just write uword as the type? (actually breaks the VARIABLESWITHINIT now that zp vars get initialized to 0 again; all the pointer examples won't compile anymore)
fix ^^Node nodes / cx16.r0L = nodes[2].weight (TODO("IR datatype for struct instances")
fix bool bb2 = bptr[2]^^ ... peekbool(bptr[2]) gives a arg 1 type error... just omit peekbool() here?
fix countries[2]^^ = 0 compiler crash

IR/VM
-----
- possible to use LOADFIELD/STOREFIELD instructions more?
- pointer dt's are all reduced to just an uword (in the irTypeString method) - is this okay or could it be beneficial to reintroduce the actual pointer type information? See commit fcda2dd92d0ec64d24dad05018a3cd6aef2fed84
- change the instruction format so an indirect register (a pointer) can be used more often, at least for the inplace assignment operators that operate on pointer
- getting it in shape for code generation...: the IR file should be able to encode every detail about a prog8 program (the VM doesn't have to actually be able to run all of it though!)
- fix call() return value handling (... what's wrong with it again?)
