[AArch64][SVE2] Asm: add various bitwise shift instructions
Summary:
This patch adds support for the SVE2 saturating/rounding bitwise shift
left (predicated) group of instructions:
* SRSHL, URSHL, SRSHLR, URSHLR, SQSHL, UQSHL, SQRSHL, UQRSHL,
SQSHLR, UQSHLR, SQRSHLR, UQRSHLR
Immediate forms of the SQSHL and UQSHL instructions are also added to
the existing SVE bitwise shift by immediate (predicated) group, as well
as three new instructions SRSHR/URSHR/SQSHLU. The new instructions in
this group are encoded similarly and are implemented using the same
TableGen class with a minimal change (1 bit in encoding).
The specification can be found here:
