Hmm, it seems more intuitive to me to have attributes for each
register.  Float, vector, system for the register's class or group, and
then we could have other not necessarily mutually exclusive flags. 
Like, available in kernel or user mode.

Just a thought though.

With an attribute scheme, once we know which registers are present in a
frame we'd know which (say) float registers are present in that
frame...
