490bebbd9a 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.

3290a9fdc2 common: Remove address_range.h 
The AddressRange structure isn't used anywhere within the codebase, so
this can be removed. Particularly because there's no real appeal/heavy
potential use of it in the future that isn't trivial to add back if
needed.

84affdb260 safe_ops: Avoid cases where shift bases are invalid with signed values 
For example, say the converted signed type is s64, shifting left  by 63
bits would be undefined behavior.

However, given an ASL is essentially the same behavior as an LSL
we can just use an unsigned type instead of converting to a signed type.

d0274f412a safe_ops: Avoid signed overflow in Negate() 
Negation of values such as -9223372036854775808 can't be represented in
signed equivalents (such as long long), leading to signed overflow.
Therefore, we can just invert bits and add 1 to perform this behavior
with unsigned arithmetic.

ade595e377 bit_util: Do nothing in RotateRight if the rotation amount is zero 
Without this sanitizing it's possible to perform a shift with a shift
amount that's the same size as the type being shifted. This actually
occurs when decoding ORR variants.

We could get fancier here and make this branchless, but we don't
really use RotateRight in any performance intensive areas.
