Log:
[AArch64][SVE] Asm: Support for predicated unary operations.
The patch includes support for the following instructions:
ABS z0.h, p0/m, z0.h
NEG z0.h, p0/m, z0.h
(S|U)XTB z0.h, p0/m, z0.h
(S|U)XTB z0.s, p0/m, z0.s
(S|U)XTB z0.d, p0/m, z0.d
(S|U)XTH z0.s, p0/m, z0.s
(S|U)XTH z0.d, p0/m, z0.d
(S|U)XTW z0.d, p0/m, z0.d
