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 support for the following instructions:
CLS (Count Leading Sign bits)
CLZ (Count Leading Zeros)
CNT (Count non-zero bits)
CNOT (Logically invert boolean condition in vector)
NOT (Bitwise invert vector)
FABS (Floating-point absolute value)
FNEG (Floating-point negate)
All operations are predicated and unary, e.g.
clz z0.s, p0/m, z1.s
- CLS, CLZ, CNT, CNOT and NOT have variants for 8, 16, 32
and 64 bit elements.
- FABS and FNEG have variants for 16, 32 and 64 bit elements.
