[FileCheck] Make FILECHECK_OPTS useful for its test suite 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

FileCheck: fix a bug with multiple --check-prefix options. Similar to r194565 Summary: Directives are being ignored, when they occur between a partial-word false match and any match on another prefix. For example, with FOO and BAR prefixes: _FOO FOO: foo BAR: bar FileCheck incorrectly matches: fog bar This happens because FOO falsely matched as a partial word at '_FOO' and was ignored while BAR matched at 'BAR:'. The match of BAR is incorrectly returned as the 'first match' causing the FOO directive to be discarded. Fixed this the same way as r194565 (D2166) did for a similar test case. The partial-word false match should be counted as a match for the purposes of finding the first match of a prefix, but should be returned as a false match using CheckTy::CheckNone so that it isn't treated as a directive.

[FileCheck] Implement -v and -vv for tracing matches -v prints all directive pattern matches. -vv additionally prints info that might be noise to users but that can be helpful to FileCheck developers. To maximize code reuse and to make diagnostics more consistent, this patch also adjusts and extends some of the existing diagnostics. CHECK-NOT failures now report variables uses. Many more diagnostics now report the check prefix and kind of directive. Reviewed By: probinson Differential Revision: https://reviews.llvm.org/D47114 llvm-svn: 336967
