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.

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.
