testsuite: Require vect_extract_even_odd in gcc.dg/vect/slp-19c.c

The gcc.dg/vect/slp-19c.c test FAILs on SPARC (32 and 64-bit):

FAIL: gcc.dg/vect/slp-19c.c scan-tree-dump-times vect "vectorized 2 loops" 1
FAIL: gcc.dg/vect/slp-19c.c scan-tree-dump-times vect "vectorizing stmts using SLP" 4

The dump shows

gcc.dg/vect/slp-19c.c:31:17: missed:   unsupported vect permute { 1 3 }
gcc.dg/vect/slp-19c.c:31:17: missed:   permutation not supported, using elementwise access
gcc.dg/vect/slp-19c.c:31:17: missed:   not falling back to elementwise accesses
gcc.dg/vect/slp-19c.c:40:25: missed:   not vectorized: relevant stmt not supported: _16 = in[_15];
gcc.dg/vect/slp-19c.c:31:17: note:   unsupported SLP instance starting from: ia[i_136] = _16;

The test needs to require vect_extract_even_odd.
