[commit] Add support for printing register flags on UltraSPARC

[Mark Kettenis <mark dot kettenis at xs4all dot nl>]

Pretty straightforward.  Bit #6 and #7 of %pstate should really be
printed as a 2-bit field with values TSO, PSO and RMO, but there is no
support code for that yet.

Committed,

Mark
