Gabe Black 48525f581c ARM: Split the condition codes out of the CPSR.
This allows those bits to be renamed while allowing the other fields to
control the behavior of the processor.

Gabe Black 4a454c4f47 ARM: Set up an intregs.hh for ARM.
Add constants for all the modes and registers, maps for aliasing, functions
that use the maps and range check, and use a named constant instead of a magic
number for the microcode register.
