[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.

[LoopUtils] Freeze compare results for diff checks instead of pointers.
THe freezes are introduced to avoid branch on undef/poison, if any of

[LoopUtils] Freeze compare results for diff checks instead of pointers.
THe freezes are introduced to avoid branch on undef/poison, if any of
the pointers may be poison. The same can be achieved by just freezing
the compare, which reduces the number of freezes needed. See
https://alive2.llvm.org/ce/z/NHa_ud
Note that the individual compares need to be frozen and it is not
sufficient to only freeze the resulting OR:
Result OR frozen only (UNSOUND): https://alive2.llvm.org/ce/z/YzFHQY
Individual conds frozen (SOUND): https://alive2.llvm.org/ce/z/5L6Z3f

[InstCombine] Set dead phi inputs to poison in more cases
Set phi inputs to poison whenever we find a dead edge (either
during initial worklist population or the main InstCombine run),
instead of only doing this for successors of dead blocks.
This means that the phi operand is set to poison even if for
critical edges without an intermediate block.
There are quite a few test changes, because the pattern is fairly
common in vectorizer output, for cases where we know the vectorized
loop will be entered.

[LAA] Add recursive IR walker for forked pointers
This builds on the previous forked pointers patch, which only accepted
a single select as the pointer to check. A recursive function to walk
through IR has been added, which searches for either a loop-invariant
or addrec SCEV.
This will only handle a single fork at present, so selects of selects
or a GEP with a select for both the base and offset will be rejected.
There is also a recursion limit with a cli option to change it.
