:wave: Hey,

This is a fix for the issue that was discovered in #5046 where iconst.i128 was causing issues and we decided to remove it.

I think most of the codegen differences are different register selection, except for the x64 tests where it de-duplicated some zeroing of registers.

Bugpoint also had to be updated to recognize the new pattern of uextend+iconst when minimizing these cases.
