  [CIR] Implement big-bitint lowering for big-endian (#225829)

As a followup to #225470, there was a post-commit comment that we didn't
do big-endian. This patch does that implementation.

However, thanks to the lack of the PPC ABI, we can't use the same test
file (the check lines for functions made the set of prefixes absurd), so
this only does the ones that are effectively different in a meaningful
way, which is a few of the constants. WE match classic in all but
irrelevant differences (packed vs not in 1 place).
