Fangrui Song ecd6d7254e [test] llvm/test/: change llvm-objdump single-dash long options to double-dash options
As announced here: http://lists.llvm.org/pipermail/llvm-dev/2019-April/131786.html

Grouped option syntax (POSIX Utility Conventions) does not play well with -long-option
A subsequent change will reject -long-option.

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:

Sander de Smalen 7fc8543208 [AArch64][SVE] Asm: Support for saturing ADD/SUB instructions.
The variants added are:
    signed Saturating ADD/SUB (immediate)  e.g. sqadd z0.h, z0.h, #42
  unsigned Saturating ADD/SUB (immediate)  e.g. uqadd z0.h, z0.h, #42
    signed Saturating ADD/SUB (vectors)    e.g. sqadd z0.h, z0.h, z1.h
  unsigned Saturating ADD/SUB (vectors)    e.g. uqadd z0.h, z0.h, z1.h
