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/testsuite:
	PR tree-optimization/98238
	* 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.
