8b990b77 - [AArch64] Select sqdmulh for smul.fix.sat with scale == eltbits-1 (#211579)

[AArch64] Select sqdmulh for smul.fix.sat with scale == eltbits-1 (#211579) Follow-up to #209351 (which vectorized the generic expansion): on AArch64, smul.fix.sat with scale == eltbits-1 is exactly sqdmulh, so select it directly instead of the generic clamp.
