[SourceMgr][FileCheck] Obey -color by extending WithColor (Relands r344930, reverted in r344935, and now hopefully fixed for Windows.) While this change specifically targets FileCheck, it affects any tool using the same SourceMgr facilities. Previously, -color was documented in FileCheck's -help output, but -color had no effect. Now, -color obeys its documentation: it forces colors to be used in FileCheck diagnostics even when stderr is not a terminal. -color is especially helpful when combined with FileCheck's -v, which can produce a long series of diagnostics that you might wish to pipe to a pager, such as less -R. The WithColor extensions here will also help to clean up color usage in FileCheck's annotated dump of input, which is proposed in D52999.

; Create a case that produces a simple diagnostic.
; RUN: echo foo > %t.in
; CHECK: bar
; Run without and with -color. In the former case, FileCheck should suppress
; color in its diagnostics because stderr is a file.
[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
