Add support for #pragma system_header with -fms-extensions Clang already supports the pragma prefixed by "GCC" or "clang". MSVC has more recently added support for the pragma, but without any prefix; see https://devblogs.microsoft.com/cppblog/broken-warnings-theory/#external-headers Differential revision: https://reviews.llvm.org/D104770

Invoke the FileChanged callback before pushing the linemarker for a system header. Getting it in the wrong order generated incorrect line markers in -E mode. In the testcase from PR9861 we used to generate: # 1 "test.c" 2 # 1 "./foobar.h" 1 # 0 "./foobar.h" # 0 "./foobar.h" 3 # 2 "test.c" 2 now we properly produce: # 1 "test.c" 2 # 1 "./foobar.h" 1 # 1 "./foobar.h" 3 # 2 "test.c" 2 This fixes PR9861. llvm-svn: 131871
