I'm speculating that a simpler specification of classes could be
informed by the needs of the new register allocator. That's all.
I don't see it. The complexity of register class specifications is
dictated by the complexity of architectures, not anything we put into GCC:
it has to be expressive enough to describe all architectures.
Sure, it's somewhat redundant, in that we have maps both ways, and a few
macros could be eliminated in that process, but it doesn't seem worth the
effort to me.
