target-alpha: Reduce internal processor registers for user-mode.
The existing set of IPRs is totally irrelevant to user-mode emulation.
Indeed, they most are irrelevant to implementing kernel-mode emulation,
and would only be relevant to PAL-mode emulation, which I suspect that
no one will ever attempt.
Reducing the set of processor registers reduces the size of the CPU state.
