Tweak new test cases for -march=cascadelake strangeness.
As reported by Sunil's tester, -march=cascadelake triggers some SUBREG
non-determinacy in the generated assembler for my new tests. Fixed
by updating the regular expressions to match either the zero or sign
extended forms. I'm testing a backend patch that may help with the
underlying cause of these differences.
