(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.
