bfaeb08d3c A64: Implement LDNP/STNP
LDNP and STNP indicate that a memory access is non-temporal/streaming
(i.e. unlikely to be repeated), allowing data caching to not be
performed. However, given this is only a hint, we can treat these two
instructions as regular LDP and STP instructions for the time being.

f0920c0ded Fix VShift terminology
An arithmetic shift is by definition a signed shift, and a logical shift is by definition an unsigned shift.

- Rename VectorLogicalVShiftS* -> VectorArithmeticVShift*

ab60720418 A64/translate/impl: Make signatures consistent for unimplemented by-element SIMD variants

6b5ea6ee66 A64: Implement BRK

b915364c16 A64/imm: Add full range of comparison operators to Imm template
Makes the comparison interface consistent by providing all of the
relevant members. This also modifies the comparison operators to take
the Imm instance by value, as it's really only a u32 under the covers,
and it's cheaper to shuffle around a u32 than a 64-bit pointer address.
