Allow tests to specify a `//@ filecheck-flags:` header This allows individual codegen/assembly/mir-opt tests to pass extra flags to the LLVM `filecheck` tool as needed. --- The original motivation was noticing that `tests/run-make/instrument-coverage` was very close to being an ordinary codegen test, except that it needs some extra logic to set up platform-specific variables to be passed into filecheck. I then saw the comment in `verify_with_filecheck` indicating that a `filecheck-flags` header might be useful for other purposes as well. |
