[PATCH] D68230: [UpdateCCTestChecks] Allow asm in output with --allow-asm

[David Greene via Phabricator via llvm-commits]

greened added projects: LLVM, clang.
Herald added a subscriber: llvm-commits.

It is useful to have update_cc_test_checks.py generate asm checks for end-to-end testing.  Add --allow-asm to generate test checks even if --emit-llvm doesn't appear on the clang command line.
