popcount and mask_gather_load_run fails seem to be an issue with my
setup or a bug with QEMU based on the v2 discussion :-)
OK with me regarding testing (I don't have the authority to approve a
patch, but Kito already said LGTM):
This patch addresses the redundant AVL/VL toggling in RVV partial
auto-vectorization
which is a known issue for a long time and I finally find the time to address
it.
Consider a simple vector addition operation:

void
foo (int *__restrict a,
int *__restrict
