[PATCH] D86621: [clang][Sparc] Default to -mcpu=v9 for SparcV8 on Solaris

[Rainer Orth via Phabricator via cfe-commits]

ro added a comment.

While doing 2-stage builds, the 2 `XFAIL`s due to Bug 42493 were required.  However, I've since also done a 1-stage build with gcc 10, which shows

  Unexpectedly Passed Tests (2):
    UBSan-Standalone-sparc :: TestCases/Float/cast-overflow.cpp
    UBSan-Standalone-sparc :: TestCases/Misc/log-path_test.cpp

which is no wonder since the underlying bug only exists in `clang` `long double` handling.

I'm a bit uncertain how to deal with this: since the Solaris/sparcv9 buildbot currently does 1-stage builds with gcc, the resulting `XPASS`es would turn the bot red.  However, currently there's no clang-vs.-gcc feature in `lit` to distinguish the two builds, AFAICT.  `libcxx` has something like this, but that might be overkill to extract.

Perhaps just remove the `XFAIL`s for now?
