Log:
Use valid_for_const_vector_p instead of CONSTANT_P

This patch makes the VEC_SERIES code use valid_for_const_vector_p
instead of CONSTANT_P, to match what we already do for VEC_DUPLICATE.
This showed up as a failure in gcc.c-torture/execute/pr28982b.c for -m32
on x86_64-linux-gnu after later patches.
