[Attributor][NFC] Update tests after D94741 The update_test_checks script can now check for global symbols and is able to handle them properly when they differ across prefixes, e.g., attribute #0 might be different in different runs. This patch simply updates all the Attributor tests with the new script. Reviewed By: sstefan1 Differential Revision: https://reviews.llvm.org/D97906

[Attributor] Provide a command line option that limits recursion depth In `MultiSource/Benchmarks/tramp3d-v4/tramp3d-v4.cpp` we initialized attributes until stack frame ~35k caused space to run out. The initial size 1024 is pretty much random.

[ValueTracking] Dereferenced pointers are noundef This is a follow-up of D95238's LangRef update. This patch updates `programUndefinedIfUndefOrPoison(V)` to return true if `V` is used by any memory-accessing instruction. Interestingly, this affected many tests in Attributors, mainly about adding noundefs. The tests are updated using llvm/utils/update_test_checks.py. I checked that the diffs are about updating noundefs. Reviewed By: nikic Differential Revision: https://reviews.llvm.org/D96642
