Description
Arches now are kind of like singletons. They probably should be. I'm told there are some cursed copies and mutations floating around in angr's x86 real mode stuff that expects the current behavior, but this behavior should be eliminated if possible.
Since arches come in variants, most commonly BE/LE, we might want to have a get_all_variants function per-arch that does the instantiation. Alternatively, we could just make the classes the singleton themselves, so an arch that varies only in endness like mips32 might have 3 classes: BaseMips32, Mips32LE, and MIPS32BE. Or the base and one of the endnesses could be merged.
