[AArch64][SVE] Asm: Support for remaining shift instructions.
This patch completes support for shifts, which include:
- LSL - Logical Shift Left
- LSLR - Logical Shift Left, Reversed form
- LSR - Logical Shift Right
- LSRR - Logical Shift Right, Reversed form
- ASR - Arithmetic Shift Right
- ASRR - Arithmetic Shift Right, Reversed form
- ASRD - Arithmetic Shift Right for Divide
In the following variants:
- Predicated shift by immediate - ASR, LSL, LSR, ASRD
e.g.
asr z0.h, p0/m, z0.h, #1
(active lanes of z0 shifted by #1)
- Unpredicated shift by immediate - ASR, LSL*, LSR*
e.g.
asr z0.h, z1.h, #1
(all lanes of z1 shifted by #1, stored in z0)
- Predicated shift by vector - ASR, LSL*, LSR*
e.g.
asr z0.h, p0/m, z0.h, z1.h
(active lanes of z0 shifted by z1, stored in z0)
- Predicated shift by vector, reversed form - ASRR, LSLR, LSRR
e.g.
lslr z0.h, p0/m, z0.h, z1.h
(active lanes of z1 shifted by z0, stored in z0)
- Predicated shift left/right by wide vector - ASR, LSL, LSR
e.g.
lsl z0.h, p0/m, z0.h, z1.d
(active lanes of z0 shifted by wide elements of vector z1)
- Unpredicated shift left/right by wide vector - ASR, LSL, LSR
e.g.
lsl z0.h, z1.h, z2.d
(all lanes of z1 shifted by wide elements of z2, stored in z0)
