[InstCombine] Infer nusw + nneg -> nuw for getelementptr (#111144)

If the gep is nusw (usually via inbounds) and the offset is
non-negative, we can infer nuw.

[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.

[SimplifyLibCalls] propagate tail flags on CallInsts

I noticed we weren't propagating tail flags on calls when
FortifiedLibCallSimplifier.optimizeCall() was replacing calls to runtime
checked calls to the non-checked routines (when safe to do so). Make
sure to check this before replacing the original calls!

Also, avoid any libcall transforms when notail/musttail is present.

Revert "[Libcalls, Attrs] Annotate libcalls with noundef"

This reverts commit 33b0c63775ce58014c55e285671e3315104a6076. Bots are failing. Some Clang tests need to be updated too.

[Libcalls, Attrs] Annotate libcalls with noundef

I think we can use here same logic as for nonnull.

strlen(X) - X must be noundef => valid pointer.

for libcalls with size arg, we add noundef only

I think we can use here same logic as for nonnull.

strlen(X) - X must be noundef => valid pointer.

for libcalls with size arg, we add noundef only if size is known and greater than 0 - so pointers must be noundef (valid ones)
