Arthur Eubanks 6c348aca4e Adjust dbg.value/dbg.declare checks for LLVM update
https://github.com/llvm/llvm-project/pull/89799 changes llvm.dbg.value/declare intrinsics to be in a different, out-of-instruction-line representation. For example
  call void @llvm.dbg.declare(...)
becomes
  #dbg_declare(...)

Update tests accordingly to work with both the old and new way.
