[InstCombine] Preserve the nsw/nuw flags for (X | Op01C) + Op1C --> X + (Op01C + Op1C) (#94586)
This patch simplifies `sdiv` to `udiv` by preserving the `nsw` flag for
`(X | Op01C) + Op1C --> X + (Op01C + Op1C)` if the sum of `Op01C` and
`Op1C` will not overflow, and preserves the `nuw` flag unconditionally.

[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.

[ValueTracking] Use computeConstantRange() in signed add overflow determination
This is D59386 for the signed add case. The computeConstantRange()
result is now intersected into the existing known bits information,
allowing to detect additional no-overflow/always-overflow conditions
(though the latter isn't used yet).
This (finally...) covers the motivating case from D59071.
