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*
