1. Be more tolerant of comments in -CC (comment-preserving) mode. We were missing a few cases.
2. Make sure to expand the second FOO in "#if defined FOO FOO". (See also
r97253, which addressed the case of "#if defined(FOO FOO".)
Fixes PR10286.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
