middle-end/110182 - TYPE_PRECISION on VECTOR_TYPE causes wrong-code
When folding two conversions in a row we use TYPE_PRECISION but
that's invalid for VECTOR_TYPE. The following fixes this by
using element_precision instead.
middle-end/110182
* match.pd (two conversions in a row): Use element_precision
to DTRT for VECTOR_TYPE.
(cherry picked from commit 3e12669a0eb968cfcbe9242b382fd8020935edf8)
