TODO
====

fix casting uword to bool (don't take only the lsb!)
fix IR adding snz in bool casts inside if


fix "wordGreaterValue"

improve code size for "wordGreaterValue"  et al.


rockrunner is a lot bigger still than on 10.1
paint is bigger than on 10.1

cx16/testmonogfx is broken
cx16/amiga is broken
assembler is broken
imageviewer is broken
paint flood fill is broken
rockrunner load caveset list is broken
medemo and dsdemo are broken

===== ====== =======


retest all comparisons in if statements (byte, word, signed and unsigned) + all comparison assignments.  Against 0 and something else as 0.
with jump, indirect jump, no else block, and both if+else blocks.

check that the flood fill routine in gfx2 and paint still works.
re-allow typecast of const true/false back to ubytes 1 and 0?
re-allow typecast of const ubyte 0/1 to false/true boolean?


IR: add TEST instruction to test memory content and set N/Z flags, without affecting any register.
    replace all LOADM+CMPI #0  / LOAD #0+LOADM+CMP+BRANCH   by this instruction
