[PATCH 0/2] target/riscv: RVV 1-fill tail element changes

[Daniel Henrique Barboza]

Hi,

This series makes changes in vext_set_tail_elements_1s() to be a little
nicer to the emulation.

First patch makes the function a no-op when vta == 0. Aside from the
logic simplification we also have a little performance boost.

Second patch makes the function debug only. The logic is explained in
the commit message, but long story short: we don't have to implement any
tail-agnostic policy at all to be spec compliant, but this function has
its uses for debug purposes, so keeping it as a debug option allow users
to disable it on demand.

Patches are based on top of Alistair's riscv-to-apply.next.
