f73104633b a32_emit_x64: Fix incorrect BMI2 implementation for SetCpsr 
* The MSB for each byte in cpsr_ge were not being appropriately set.
* We also expand test coverage to test this case.
* We fix the disassembly of the MSR (imm) and MSR (reg) instructions as well.

2188765e28 ir/value: Use type alias CoprocessorInfo for std::array<u8, 8> 
Provides a more descriptive label for the interface, and avoids the need
to hardcode the array size in multiple places.

9db6d1e98b translate_arm: Remove unnecessary rotr() function 
We already have RotateRight() in our common code, so we can remove this
function and replace it with it. We can also implement ArmExpandImm_C()
in terms of ArmExpandImm().

5eb0bdecdf IR: Simplify types. F32 -> U32, F64 -> U64, F128 -> U128 
ARM's Architecture Specification Language doesn't distinguish between floats and integers
as much as we do. This makes some things difficult to implement. Since our register
allocator is now capable of allocating values to XMMs and GPRs as necessary, the
Transfer IR instructions are no longer necessary as they used to be and they can be
removed.
