common/fp/op/FPRecipExponent: Prevent undefined behavior from shifting a negative value
...
Due to promotion rules (types < int, even if unsigned, get promoted to
int when arithmetic is performed on them), this is a potential spot for
undefined behavior.

common/fp/op/FPConvert: Amend off-by one in double NaN case in FPConvertNaN
...
Avoids potentially clobbering the intended sign bit value during
conversions to double-precision values. The other conversion types are
already properly handled, so those don't need to be addressed.

Corresponds to the equivalent pseudocode within the ARMv8 reference

common/fp/unpacked: Add FPUnpackCV
...
Adds a template function that performs the same behavior as in the ARM
pseudocode, and utilizes it in FPConvert, which will be necessary for
half-float support.
