A64: Enable FMOV (general) for half-precision floating point 
This just transfers values between vector registers and general-purpose
registers with no conversions performed, so this is trivial to add
support for half-precision to.

common/fp/unpacked: Correct edge-cases within FPUnpack for half-precision floating point 
This corrects one case where floating-point exceptions could be set when
they're not supposed to be.

This also corrects a case where values were being treated as NaNs when
they weren't supposed to be.

common/fp/unpacked: Adjust FPUnpack to operate like ARM pseudocode 
This function is defined as always disabling the AHP bit in the fpcr
before performing any operations.

At the same time, rename the original FPUnpack function to FPUnpackBase
to match the pseudocode in the ARM reference manual.

Corresponds to the equivalent pseudocode within the ARMv8 reference
