Move a bunch of tests to directly use the CC1 layer. This at least saves a subprocess invocation which is pretty significant on Windows. It also likely saves a bunch of thrashing the host machine needlessly. Finally it makes the tests much more predictable and less dependent on the host. For example 'header_lookup1.c' was passing '-fno-ms-extensions' just to thwart the host detection adding it into the compilation. By runnig CC1 directly we don't have to deal with such oddities. llvm-svn: 199308 2014-01-15 17:08:07 +08:00			`// RUN: %clang_cc1 %s -E \| grep 'stddef.h.*3'`
This really seems like a boring set of fixes to our tests to make them more independent of the underlying system. Let me know if any of these are too aggressive. llvm-svn: 119345 2010-11-16 18:26:08 +08:00			`#include <stddef.h>`
