Hello,

This patch just fills in a gap in the current *_REGNUMs by adding
PS_REGNUM. Unlike the others. This one really does allow -1 as the
default value.

(FP_REGNUM et.al. require real values as there is code around that,
unfortunatly, depends on there being a real FP register et.al. ulgh).

committed,
Andrew
