[llvm] r348564 - [llvm-mca] Improve test (NFC)

[Hans Wennborg via llvm-commits]

This test seems to fail on Mac for some reason, (see e.g.
https://logs.chromium.org/logs/chromium/bb/tryserver.chromium.mac/mac_upload_clang/431/+/recipes/steps/package_clang/0/stdout)

Exit Code: 1

Command Output (stderr):
--

error: M1-NEXT: expected string not found in input

Passing an -mtriple flag seems to help, so I've committed that in r348577.
