This changes clang to match GCC's behavior for __extension__, which temporarily disables the -pedantic flag. Warnings that are enabled without -pedantic are not affected. Besides the general goodness of matching GCC's precedent, my motivation for this is that macros in the arm_neon.h header need to use __extension__ to avoid pedantic complaints about their use of statement expressions, yet we still want to warn about incompatible pointer arguments for those macros. llvm-svn: 141804
