IRNormalizer: Replace cl::opts with pass parameters (#133874)

Not sure why the "fold-all" option naming didn't match the
variable "FoldPreOutputs", but I've preserved the difference.

More annoyingly, the pass name "normalize" does not match the pass
name IRNormalizer and should probably be fixed one way or the other.

Also the existing test coverage for the flags is lacking. I've added
a test that shows they parse, but we should have tests that they
do something.
