[InstCombine] limit zext-of-icmp folds to bit-hacks
In the changed tests, we avoid creating extra instructions,
and there are no obvious regressions in IR tests at least.
Codegen should be able to create the shift+mask form if that
is profitable.
This is a more general fix for issue #59897 than 0eedc9e56712 .
