Hi all,
This patch series reimplements the MD patterns for the instructions that
perform narrowing right shifts with optional rounding and saturation
using standard RTL codes rather than unspecs. This includes the scalar
forms and the *2 forms that write to the high half of the result vector.
Some instructions from the previous patch have scalar forms:
SQSHRN,SQRSHRN,UQSHRN,UQRSHRN,SQSHRUN,SQRSHRUN.
This patch converts the patterns for these to use standard RTL codes.
Their MD patterns deviate slightly from the vector forms mostly due to
things like operands being scalar rather than
Similar to the low-half patterns, we want to match both ashiftrt and
lshiftrt with the truncate for SHRN2. We reuse the SHIFTRT iterator

high-half patterns by their gen_* names we need to disambiguate all the
