For next release
^^^^^^^^^^^^^^^^
- can we optimize redundant calls to boolean() away? imageviewer.prg got larger because of them
- vm: fix and/or/xor to be bitwise again (need to remove optimization from VariousCleanups too?)
- vm: fix not to be bitwise not instead of boolean not
- 6502: fix not codegen to be bitwise not instead of boolean not (maybe need to change boolean() wrapping / variouscleanups)
all these testable with compiler/test/arithmetic/logical.p8
- add some more optimizations in vmPeepholeOptimizer
- vm Instruction needs to know what the read-registers/memory are, and what the write-register/memory is.
this info is needed for more advanced optimizations and later code generation steps.
