[ARM] Improve error messages for .arch_extension directive - More informative message when extension name is not an identifier token. - Stop parsing directive if extension is unknown (avoid duplicate error messages). - Report unsupported extensions with a source location, rather than report_fatal_error. Differential Revision: https://reviews.llvm.org/D22806 llvm-svn: 276748
