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:

This patch adds instructions for comparing elements from two vectors, e.g.
cmpgt p0.s, p0/z, z0.s, z1.s
and also adds support for comparing to a 64-bit wide element vector, e.g.
cmpgt p0.s, p0/z, z0.s, z1.d
The patch also contains aliases for certain comparisons, e.g.:
cmple p0.s, p0/z, z0.s, z1.s => cmpge p0.s, p0/z, z1.s, z0.s
cmplo p0.s, p0/z, z0.s, z1.s => cmphi p0.s, p0/z, z1.s, z0.s
cmpls p0.s, p0/z, z0.s, z1.s => cmphs p0.s, p0/z, z1.s, z0.s
cmplt p0.s, p0/z, z0.s, z1.s => cmpgt p0.s, p0/z, z1.s, z0.s
