I'm dropping this PR since extending the pseudo attributes/classes to reals for both instructions and registers needs more than just changing the AMDGPU tablegen files. It also requires modification of machine verifier functions in the AMDGPU backend to work in codegen and maybe some redesigning of tablegen classes and records. 

Instead of trying to modify the AMDGPU backend, I wrote a tablegen backend which maps all registers/opcodes to their pseudo equivalent on my end, hence this PR is not needed anymore.
