[InstCombine] convert static function to internal class function; NFC
The transform can require an optional shuffle instruction to be sound,
so we need to use Builder to create all values and then replace the
original instruction with whatever that final value is.

Log Message:
-----------
[InstCombine] prevent infinite looping from opposing cmp and select transforms (PR52684)
As noted in the code comment, we might want to simply give up on this select
transform completely (given how many exceptions there are already and the
risk of future conflicts), but for now, carve out one more bailout to
avoid an infinite loop.
Fixes #52684:
