Hi,

PR89834 identifies a problem with test case gcc.dg/vect/pr81740-2.c, which relies
implicitly on vectorizing unaligned accesses.  This causes it to fail when the
target processor does not support this.  The attached patch requires vect_hw_misalign
so that the test is skipped on such targets.

Tested on powerpc64le-unknown-linux-gnu (P9) and powerpc64-unknown-linux-gnu (P7),
correct behavior verified.  Committed as requested in the bugzilla (r269978).

Thanks,
Bill
