Migrate 3C regression tests from %clang_cc1 to %clang.
Browse files Browse the repository at this point in the history
This requires replacing `%clang_cc1 -verify` with `%clang -Xclang
-verify` in the tests that use it.

This is one part of the RUN command cleanup that we've wanted to do for
a while in #346, and now it is blocking part of #576. This is because
the single behavior difference we know of between %clang_cc1 and %clang
(other than the need for `-Xclang`) is that %clang_cc1 turns off the
system headers, and we want two of our tests that currently use
%clang_cc1 to be able to get checked declarations from the system
headers.

As recently as dac3f97 (August 2020),
all of the tests that used %clang_cc1 used -verify. Since then, a few
tests have been added that use %clang_cc1 and not -verify. This lends
support to my theory that the only reason we used %clang_cc1 was that we
were unaware that -verify could be used with %clang via -Xclang, and
some subsequently added tests copied the use of %clang_cc1 only because
the authors didn't know any better. Thus, I believe that the risk of the
migration affecting the validity of the tests (e.g., causing them to
falsely pass) is low.
