  [IR] Mark llvm.pseudoprobe arguments as immarg (#224669)

Per LangRef, llvm.pseudoprobe requires constant integer arguments.
Enforce this by marking them as immarg.

In particular, this prevents invalid sinking of llvm.pseudprobe calls in
GVNSink, which would introduce a phi node for a pseudoprobe argument.

Fixes #166306.
