Make more use of VECTOR_CST_ENCODED_ELT
This patch makes various bits of code operate directly on the new
VECTOR_CST encoding, instead of using VECTOR_CST_ELT on all elements
of the vector.
Previous patches handled operations that produce a new VECTOR_CST,
while this patch handles things like predicates. It also makes
print_node dump the encoding instead of the full vector that
the encoding represents.
