/* Check that for dynamic logical right shifts with a constant the negated
constant is loaded directly, instead of loading the postitive constant
and negating it separately. This was a case that happened at optimization
level -O2 and looked like:
cmp/eq r6,r5
mov #30,r1
neg r1,r1
shld r1,r4
mov r4,r0
