Sander de Smalen	e64206a02c	[AArch64][SVE] Asm: Enable instructions to be prefixed. This patch enables instructions that are destructive on their destination- and first source operand, to be prefixed with a MOVPRFX instruction. This patch also adds a variety of tests: - positive tests for all instructions and forms that accept a movprfx for either or both predicated and unpredicated forms. - negative tests for all instructions and forms that do not accept an unpredicated or predicated movprfx. - negative tests for the diagnostics that get emitted when a MOVPRFX instruction is used incorrectly.

[AArch64][SVE] Asm: Enable instructions to be prefixed.

This patch enables instructions that are destructive on their
destination- and first source operand, to be prefixed with a
MOVPRFX instruction.

This patch also adds a variety of tests:

- positive tests for all instructions and forms that accept a
  movprfx for either or both predicated and unpredicated forms.

- negative tests for all instructions and forms that do not accept
  an unpredicated or predicated movprfx.

- negative tests for the diagnostics that get emitted when a MOVPRFX
  instruction is used incorrectly.

This is patch [2/2] in a series to add MOVPRFX instructions:
- Patch [1/2]: https://reviews.llvm.org/D49592
- Patch [2/2]: https://reviews.llvm.org/D49593

[AArch64][SVE] Asm: Support for vector element FP compare.

Contains the following variants:

- Compare with (elements from) other vector
  instructions: fcmeq, fcmgt, fcmge, fcmne, fcmuo.
  aliases: fcmle, fcmlt.

  e.g. fcmle   p0.h, p0/z, z0.h, z1.h => fcmge p0.h, p0/z, z1.h, z0.h

- Compare absolute values with (absolute values from) other vector.
  instructions: facge, facgt.
  aliases: facle, faclt.

  e.g. facle   p0.h, p0/z, z0.h, z1.h => facge   p0.h, p0/z, z1.h, z0.h

- Compare vector elements with #0.0
  instructions: fcmeq, fcmgt, fcmge, fcmle, fcmlt, fcmne.

  e.g. fcmle   p0.h, p0/z, z0.h, #0.0
