The following further strengthens the check which convert expressions
we allow to vectorize as simple copy by resorting to
tree_nop_conversion_p on the vector components.
Bootstrapped on x86_64-unknown-linux-gnu, testing in progress.

The vectorizer handles a _Float16 to __bf16 conversion through
vectorizable_assignment, thinking it's a noop. The following
fixes this by making the same-size check stricter, requiring
the same vector component mode.
