[InstCombine] Simplify nested selects with implied condition (#83739)
This patch does the following simplification:
```
sel1 = select cond1, X, Y
sel2 = select cond2, sel1, Z
-->
sel2 = select cond2, X, Z if cond2 implies cond1
sel2 = select cond2, Y, Z if cond2 implies !cond1
```
Alive2: https://alive2.llvm.org/ce/z/9A_arU
It cannot be done in CVP/SCCP since we should guarantee that `cond2` is
not an undef.

[InstCombine] Regenerate all test checks (NFC)
Due to an improvement to name preservation, a lot of InstCombine
tests now show spurious diffs when regenerated.
Rather than regenerating individual files when they get touched,
mass-regenerate all UTC-based InstCombine tests. I have then reset
a number of files showing suspicious diffs where the UTC output
has clearly been manually adjusted. I apologize if I missed
anything in the mass of changes.
