[PATCH] testsuite: vect: Require vect_hw_misalign in gcc.dg/vect/vect-cost-model-1.c etc. [PR98238]

[Rainer Orth]

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.

Ok for trunk?
