vect: Use original LHS type for gather pattern [PR118950].

In PR118950 we do not zero masked elements in a gather load.
While recognizing a gather/scatter pattern we do not use the original
type of the LHS.  This matters because the type can differ with bool
patterns (e.g. _Bool vs unsigned char) and we don't notice the need
for zeroing out the padding bytes.

This patch just uses the original LHS's type.
