arch/alpha/isa_desc:
Update for parser changes. Move most constructors

arch/isa_parser.py:
Significant changes to make ISA description completely
independent of CPU model, and isolate model-dependent parts

This replaces the scalar() and functor() terms that were
previously used in formulas. This helps when dumping
