Log:
[AArch64][SVE2] Asm: add unpredicated integer multiply instructions
Summary:
Add support for the following instructions:
* MUL (indexed and unpredicated vectors forms)
* SQDMULH (indexed and unpredicated vectors forms)
* SQRDMULH (indexed and unpredicated vectors forms)
* SMULH (unpredicated, predicated form added in SVE)
* UMULH (unpredicated, predicated form added in SVE)
* PMUL (unpredicated)
The specification can be found here:
