This adds -nostdsysteminc to the %clang_cc1 expansion, which should
make it harder to accidentally write tests that depend on headers in
/usr/include. It also updates a few tests that use -isysroot <x> and a
darwin triple to omit the triple and use -isystem <x>/usr/include
instead, making them a little bit more general.
Incidentally, this fixes a test failure I'm seeing on darwin in
Modules/stddef.c, that happens because my system finds a stddef.h in
/usr/include.

Hopefully the last tweak needed to get this test working everywhere.
Remove matching of the prefix of sys_header.h, which was never the point
of the test anyway. This avoids dealing with path separators.

We don't stat the system headers to check for stalenes during regular
PCH loading for performance reasons. When explicitly saying
-verify-pch, we want to check all the dependencies - user or system.

This option will:
- load the given pch file
- verify it is not out of date by stat'ing dependencies, and
- return 0 on success and non-zero on error
