do not emit -Wunused-macros warnings in -frewrite-includes mode (PR15614) -frewrite-includes calls PP.SetMacroExpansionOnlyInDirectives() to avoid macro expansions that are useless in that mode, but this can lead to -Wunused-macros false positives. As -frewrite-includes does not emit normal warnings, block -Wunused-macros too. Differential Revision: https://reviews.llvm.org/D65371 llvm-svn: 372026
