Add more signatures for for PAST op types.

Inlined.

I'll probably apply this in a few days if there are no objections.

Patch approved, with one correction:

>  +    piropsig['typeof']     = '~P'

"~" is not really a valid return type specifier -- it needs to be
an explicit register type (e.g., either 'S' or 'P').

Thanks!
