tree-optimization/101636 - CTOR vectorization ICE
The following fixes an ICE when vectorizing the defs of a CTOR
results in a different vector type than expected. That can happen
with AARCH64 SVE and a fixed vector length as noted in r10-5979
and on x86 with AVX512 mask CTORs and trying to re-vectorize
using SSE as shown in this bug.
The fix is simply to reject the vectorization when it didn't
produce the desired type.
