LibX86: Disassemble most remaining FPU instructions

Browse source 
Some of the remaining instructions have different behavior for
register and non-register ops.  Since we already have the
two-level flags tables, model this by setting all handlers in
the two-level table to the register op handler, while the
first-level flags table stores the action for the non-reg handler.
