Use element_precision for match.pd arith conversion optimization
The simplification (outertype)((innertype0)a+(innertype1)b) to
((newtype)a+(newtype)b) ends up using TYPE_PRECISION to check
whether it can elide a conversion but in some paths there can
be VECTOR_TYPEs where this instead compares the number of lanes.
The following fixes the missed optimizations and uses
element_precision in those places.
* match.pd ((outertype)((innertype0)a+(innertype1)b)
-> ((newtype)a+(newtype)b)): Use element_precision
where appropriate.
