Macros are nasty, so let's get rid of them. Convert all

all macros in ev5.hh to inline functions or constant typed
variables and make them follow our style while we're at it.

All of the stuff in this file actually belongs in the ISA
traits code, but this is a first step at getting things done
in the right manner.

    be less isa specific and use the isa traits to figure out
