Two ubsan tests FAIL on Sparc:

  UBSan-Standalone-sparc :: TestCases/TypeCheck/misaligned.cpp
  UBSan-Standalone-sparcv9 :: TestCases/TypeCheck/misaligned.cpp

I've reported the details in Bug 47015, but it seems to boil down to the fact that the
`s1` subtest actually incurs a fault on strict-alignment targets like Sparc which UBSan
doesn't expect.

I've found no way to `XFAIL` just that single subtest, so this patch `XFAIL`s the whole
testcase.

Tested on `sparcv9-sun-solaris2.11` and `amd64-pc-solaris2.11`.
