[llvm-branch-commits] [dse] Skip llvm.allow.{runtime, ubsan}.check() (PR #86067)

[Vitaly Buka via llvm-branch-commits]

https://github.com/vitalybuka created https://github.com/llvm/llvm-project/pull/86067

Doing this because it's similar to `assume`, but I
can't see a difference neither for `assume` nor for
`allow`.
