[AArch64][SVE2] Asm: support SVE2 Narrowing Group
Summary:
Patch adds support for the following instructions:
SVE2 bitwise shift right narrow:
* SQSHRUNB, SQSHRUNT, SQRSHRUNB, SQRSHRUNT, SHRNB, SHRNT, RSHRNB, RSHRNT,
SQSHRNB, SQSHRNT, SQRSHRNB, SQRSHRNT, UQSHRNB, UQSHRNT, UQRSHRNB,
UQRSHRNT
SVE2 integer add/subtract narrow high part:
* ADDHNB, ADDHNT, RADDHNB, RADDHNT, SUBHNB, SUBHNT, RSUBHNB, RSUBHNT
SVE2 saturating extract narrow:
* SQXTNB, SQXTNT, UQXTNB, UQXTNT, SQXTUNB, SQXTUNT
The specification can be found here:
