[19/46] Make vect_dr_stmt return a stmt_vec_info
This patch makes vect_dr_stmt return a stmt_vec_info instead of a
gimple stmt. Rather than retain a separate gimple stmt variable
in cases where both existed, the patch replaces uses of the gimple
variable with the uses of the stmt_vec_info. Later patches do this
more generally.
Many things that are keyed off a data_reference would these days
be better keyed off a stmt_vec_info, but it's more convenient
to do that later in the series. The vect_dr_size calls that are
left over do still benefit from this patch.
