    testsuite: Require vect_hw_misalign in gcc.dg/vect/vect-71.c [PR123197]
    
    The gcc.dg/vect/vect-71.c test currently FAILs on SPARC (32 and 64-bit):
    
    FAIL: gcc.dg/vect/vect-71.c scan-tree-dump-times vect "vectorized 1 loops" 1
    
    The dump shows
    
    gcc.dg/vect/vect-71.c:18:17: missed:   unsupported unaligned access
    gcc.dg/vect/vect-71.c:20:17: missed:   not vectorized: relevant stmt not supported: ia[_1] = 0;
    
    so the test needs to require vect_hw_misalign.
    
    Tested on sparc-sun-solaris2.11 and i386-pc-solaris2.11.
