test: Isolate slp-1.c check of target supports vect_strided5
This test failed in RISC-V:
FAIL: gcc.dg/vect/slp-1.c -flto -ffat-lto-objects scan-tree-dump-times vect "vectorizing stmts using SLP" 4
FAIL: gcc.dg/vect/slp-1.c scan-tree-dump-times vect "vectorizing stmts using SLP" 4
Because this loop:
/* SLP with unrolling by 8. */
for (i = 0; i < N; i++)
{
out[i*5] = 8;
out[i*5 + 1] = 7;
out[i*5 + 2] = 81;
out[i*5 + 3] = 28;
out[i*5 + 4] = 18;
}
is using vect_load_lanes with array size = 5.
instead of SLP.
When we adjust the COST of LANES load store, then it will use SLP.
gcc/testsuite/ChangeLog:
* gcc.dg/vect/slp-1.c: Add vect_stried5.
