[AArch64][SVE] Asm: Support for unpredicated FP operations.
This patch adds support for the following unpredicated
floating-point instructions:
FADD Floating point add
FSUB Floating point subtract
FMUL Floating point multiplication
FTSMUL Floating point trigonometric starting value
FRECPS Floating point reciprocal step
FRSQRTS Floating point reciprocal square root step
The instructions have the following assembly format:
fadd z0.h, z1.h, z2.h
and have variants for 16, 32 and 64-bit FP elements.
