gcc11-pr98287.patch

I'd be afraid it could be hundreds of patterns potentially affected by this.
So I think it is much easier to handle that in the infrastructure.

This patch attempts to do that when PROP_gimple_lvec property is set for cases
for which expand_vector_operations_1 does something (except I've skipped the
VEC_PERM_EXPR and VEC_COND_EXPR/COND_EXPR checks for now).
