arm: Auto-vectorization for MVE: vclz
This patch adds support for auto-vectorization of clz for MVE.
It does so by removing the unspec from mve_vclzq_<supf><mode> and uses
'clz' instead. It moves to neon_vclz<mode> expander from neon.md to
vec-common.md and renames it into the standard name clz<mode>2.
