Without this patch, `FILECHECK_OPTS` isn't propagated to FileCheck's test suite so that `FILECHECK_OPTS` doesn't inadvertently affect test results by affecting the output of FileCheck calls under test. As a result, `FILECHECK_OPTS` is useless for debugging FileCheck's test suite. In `llvm/test/FileCheck/lit.local.cfg`, this patch provides a new subsitution, `%ProtectFileCheckOutput`, to address this problem for both `FILECHECK_OPTS` and the deprecated `FILECHECK_DUMP_INPUT_ON_FAILURE`. The rest of the patch uses `%ProtectFileCheckOutput` throughout the test suite Fixes PR40284. Reviewed By: probinson, thopre Differential Revision: https://reviews.llvm.org/D65121
