r276653 suppressed the pragma once warning when generating a PCH file. This patch extends that to any main file for which clang is told (with the -x option) that it's a header file. It will also suppress the warning "#include_next in primary source file". Differential Revision: http://reviews.llvm.org/D25989 llvm-svn: 285295
