The vnclip instruction does a fixed-point saturating add then shift and
 can replace vwadd followed by vnsra in idct_4, idct_8, idct_16, iadst_8
 and iadst_16.
Including 572c5a66 (which applies the same change to iadst_4) these
 commits give the following average improvements across all modified 2D
 transform functions:

To avoid read-after-write. Speedup is about 1% for width=4 on a K230.

This code compromises between the performance of a dedicated kernel per
VLEN/width pair, and the flexibility of a fully VLEN-dynamic loop, by
using a single special case for w=4, and subdividing the rest into the
unrolled four line fast path, and the general-purpose slow path (for
large width on small VLEN).

Instead of using gathers we can calculate the value of
sgr_x_by_x[min(z, 255)] by doing 256 / (z + 1) in floating-point
with some clipping for z == 0 and z >= 255.

As the required precision of the division is fairly small it can be
performed using an approximate reciprocal, which is significantly
faster than a regular division.

Gather instructions are slow on all AMD CPU:s, and on most Intel
CPU:s ever since µcode updates were issued as a workaround for
the Gather Data Sampling side channel vulnerability.
