Sander de Smalen 5dabcf887b [AArch64][SVE] Asm: Support for predicated FP operations (FP immediate) 
This patch completes support for the following floating point
instructions that take FP immediates:
  FADD*  (addition)
  FSUB   (subtract)
  FSUBR  (subtract reverse form)
  FMUL*  (multiplication)
  FMAX*  (maximum)
  FMAXNM (maximum number)
  FMIN   (maximum)
  FMINNM (maximum number)

All operations are predicated and take a FP immediate operand,
e.g.

  fadd z0.h, p0/m, z0.h, #0.5
  fmin z0.s, p0/m, z0.s, #1.0
        ^___________^ (tied)

* Instructions added in a previous patch.

Sander de Smalen 3b9e342ae1 [AArch64][SVE] Asm: Support for predicated FP operations. 
This patch adds support for the following floating point
instructions:
  FABD   (absolute difference)
  FADD   (addition)
  FSUB   (subtract)
  FSUBR  (subtract reverse form)
  FDIV   (divide)
  FDIVR  (divide reverse form)
  FMAX   (maximum)
  FMAXNM (maximum number)
  FMIN   (minimum)
  FMINNM (minimum number)
  FSCALE (adjust exponent)
  FMULX  (multiply extended)

All operations are predicated and binary form, e.g.

  fadd z0.h, p0/m, z0.h, z1.h
        ^___________^ (tied)

Supporting 16, 32 and 64-bit FP elements.
