ipa/119067 - bogus TYPE_PRECISION check on VECTOR_TYPE

odr_types_equivalent_p can end up using TYPE_PRECISION on vector
types which is a no-go.  The following instead uses TYPE_VECTOR_SUBPARTS
for vector types so we also end up comparing the number of vector elements.

PR ipa/119067
* ipa-devirt.cc (odr_types_equivalent_p): Check
TYPE_VECTOR_SUBPARTS for vectors.

* g++.dg/lto/pr119067_0.C: New testcase.
* g++.dg/lto/pr119067_1.C: Likewise.
