  Log Message:
  -----------
  [InstCombine] avoid crash on fold of icmp with cast operand

We could do better by inserting a bitcast from scalar int
to vector int or using an insertelement (the alternate test
does not crash because there's an independent fold like that).

But this doesn't seem like a likely pattern, so just bail out
for now.

Fixes issue #55516.
