New -assume-filename=param to check_clang_tidy.py (like clang-format) Summary: Currently, check_clang_tidy.py includes logic to select default clang flags based on the extension of the source filename passed as the first argument. Since the source filename might be a temporary or test file with an arbitrary extension unrelated to the file type, this adds the ability to override the logic the same way `clang-format`'s -assume-filename= parameter does. I included a test with a nonstandard file extension. I confirmed when I modified the warning message that the new test failed, and that it passed again when I restored the warning message. Ran tests with: % cmake -G Ninja /path/to/llvm % ninja check-clang-tools Patch by Ben Hamilton!
