    testsuite: vect: Require vect_hw_misalign in gcc.dg/vect/vect-cost-model-1.c etc. [PR98238]
    
    Several gcc.dg/vect/vect-cost-model-?.c tests FAIL on 32 and 64-bit
    Solaris/SPARC:
    
    FAIL: gcc.dg/vect/vect-cost-model-1.c -flto -ffat-lto-objects
    scan-tree-dump vect "LOOP VECTORIZED"
    FAIL: gcc.dg/vect/vect-cost-model-1.c scan-tree-dump vect "LOOP VECTORIZED"
    FAIL: gcc.dg/vect/vect-cost-model-3.c -flto -ffat-lto-objects
    scan-tree-dump vect "LOOP VECTORIZED"
    FAIL: gcc.dg/vect/vect-cost-model-3.c scan-tree-dump vect "LOOP VECTORIZED"
    FAIL: gcc.dg/vect/vect-cost-model-5.c -flto -ffat-lto-objects
    scan-tree-dump vect "LOOP VECTORIZED"
    FAIL: gcc.dg/vect/vect-cost-model-5.c scan-tree-dump vect "LOOP VECTORIZED"
    
    The dumps show
    
    /vol/gcc/src/hg/master/local/gcc/testsuite/gcc.dg/vect/vect-cost-model-1.c:7:30:
    note: ==> examining statement: _3 = *_2;
    /vol/gcc/src/hg/master/local/gcc/testsuite/gcc.dg/vect/vect-cost-model-1.c:7:30:
    missed: unsupported unaligned access
    /vol/gcc/src/hg/master/local/gcc/testsuite/gcc.dg/vect/vect-cost-model-1.c:8:6:
    missed: not vectorized: relevant stmt not supported: _3 = *_2;
    
    so I think the tests need to require vect_hw_misalign.  This is what
    this patch does.
    
    Tested on sparc-sun-solaris2.11 and i386-pc-solaris2.11.

            * gcc.dg/vect/vect-cost-model-1.c (scan-tree-dump): Also require
            vect_hw_misalign.
            * gcc.dg/vect/vect-cost-model-3.c: Likewise.
            * gcc.dg/vect/vect-cost-model-5.c: Likewise.
