349d4b577a General: Remove unnecessary includes 
Removes unnecessary header dependencies that have accumulated over time
as changes have been made. Lessens the amount of files that need to be
rebuilt when the headers change.

d9d59bc1f4 common/cast_util: Declare BitCast and BitCastPointee with the noexcept specifier 
std::bit_cast is also defined with the noexcept specifier, so we can do
the same here to match up with it and stay similar with the standard
library.

6b9a40bdc4 common/fp/op/FPNeg: Make FPNeg constexpr 
Negation in (standard IEEE) floating-point is simply flipping the sign-bit, so this
operation will never be more complex than what is presented here, making
constexpr a reasonable allowance.

c9777ef997 common/fp/info: Make half-precision info struct functions return correctly sized types 
While initially done to potentially prevent creating bugs due to C++
having a silly type-promotion mechanism involving types < sizeof(int)
and unsignedness, given that the bulk of these functions' usages
are on exit paths, these can return the correct type to avoid the need
to cast at every usage point.

46eae8cf2f 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.

dff5da1063 common/fp/unpacked: Amend behavior of FPUnpackCV 
This is supposed to call FPUnpackBase instead of FPUnpack. This would
result in alternate half-precision representations being misinterpreted
when it comes to dealing with NaNs.

03bc2334fe 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.

a829c93406 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.

to match the pseudocode in the ARM reference manual.
