The patterns added in D110163 <https://reviews.llvm.org/D110163> were incorrect, since it used the wrong
element widths for its shuffles.
Example for nxv2f16 extract_subvector(nxv8f16 %in, 6):
<a|b|c|d|e|f|g|h>
^^^
extract g and h.
> UUNPKHI .h -> .s results in:
==============================
<e |f |g |h >
> UUNPKHI .s -> .d results in:
==============================
<g |h >
