    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 VECTORI=
ZED"
    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 VECTORI=
ZED"
    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 VECTORI=
ZED"

    The dumps show

=20=20=20
/vol/gcc/src/hg/master/local/gcc/testsuite/gcc.dg/vect/vect-cost-model-1.c:=
7:30:
    note: =3D=3D> examining statement: _3 =3D *_2;
=20=20=20
/vol/gcc/src/hg/master/local/gcc/testsuite/gcc.dg/vect/vect-cost-model-1.c:=
7:30:
    missed: unsupported unaligned access
=20=20=20
/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 =3D *_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.
