Joel E. Denny 718a779582 [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.
