f3f60cd179 A64: Implement ISB
Given we want to ensure that all instructions are fetched again, we can
treat an ISB instruction as a code cache flush.

2188765e28 ir/value: Use type alias CoprocessorInfo for std::array<u8, 8>

to hardcode the array size in multiple places.

463b9a3d02 ir: Add opcodes for vector paired maximum and minimums
For the time being, we can just do a naive implementation which avoids
falling back to the interpreter a bit. Horizontal operations aren't
necessarily x86 SIMD's forte anyways.

4606a081c9 A64: The A64SetTPIDR IR instruction writes to a system register and should not be eliminated by the dead code elimination pass.

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.

0992987c98 A64: Add ExceptionRaised IR instruction
The purpose of this instruction is to raise exceptions when certain decode-time
issues happen, instead of asserting at translate time. This allows us to
use the translator for code analysis without worrying about unnecessary asserts,
but also provides flexibility for the library user to perform custom behaviour
when one of these states are raised.
