Each ISA predicate is assigned a bit the the Flags struct, and a corresponding
method is generated.

8457f67e34 Introduce predicates. 
Predcates are boolean functions. There will be ISA predicates and instruction
predicates.

The ISA predicates will be turned into member functions on the generated Flags
structs.
