Tests: rewrite 'opt ... %s' to 'opt ... < %s' so that opt does not emit a ModuleID
...
This is done to avoid odd test failures, like the one fixed in r171243.
My previous regex was not good enough to find these.

Generalize this optimization to work on equality comparisons between any two
...
integers that are constant except for a single bit (the same n-th bit in each).

Reapply r88830 with a bugfix: this transform only applies to icmp eq/ne. This

fixes part of PR5438.

Revert r88830 and r88831 which appear to have caused a selfhost buildbot some
...
grief. I suspect this patch merely exposed a bug else.

Teach instcombine to look for booleans in wider integers when it encounters a
...
zext(icmp). It may be able to optimize that away. This fixes one of the cases
in PR5438.
