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.

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

Sander de Smalen e2c10f8f47 This is a recommit of r336322, previously reverted in r336324 due to 
a deficiency in TableGen that has been addressed in r336334.

[AArch64][SVE] Asm: Support for predicated FP rounding instructions.

This patch also adds instructions for predicated FP square-root and
reciprocal exponent.

The added instructions are:
- FRINTI  Round to integral value (current FPCR rounding mode)
- FRINTX  Round to integral value (current FPCR rounding mode, signalling inexact)
- FRINTA  Round to integral value (to nearest, with ties away from zero)
- FRINTN  Round to integral value (to nearest, with ties to even)
- FRINTZ  Round to integral value (toward zero)
- FRINTM  Round to integral value (toward minus Infinity)
- FRINTP  Round to integral value (toward plus Infinity)
- FSQRT   Floating-point square root
- FRECPX  Floating-point reciprocal exponent

Sander de Smalen 097ab704c9 Reverting r336322 for now, as it causes an assert failure 
in TableGen, for which there is already a patch in Phabricator
(D48937) that needs to be committed first.
