[llvm] llvm: [NFC] Robustify testcase (PR #71120)

[Nathan Sidwell via llvm-commits]

https://github.com/urnathan created https://github.com/llvm/llvm-project/pull/71120

This is llvm's instance of unfortunate testfailure with a pathname containing 'alias'. Clang's case was addressed with https://github.com/llvm/llvm-project/pull/69739.  CHECK-NOT regexes can be tricky.

Expect llvm-as diagnostic and robustify 'alias' check-not, to avoid problems with pathnames.
