Right now, the pass does not optimize tail recursions

add(Pass *) as a pure virtual member function. This will allow all
the various addPassesTo* functions in LLVM to avoid hard-coding what
type of PassManager is used.

If there are multiple register classes that a register belongs to, return the super-class (e.g. on x86, returns GR32, not GR32_).

When the register allocator runs out of registers, spill a physical register around the def's and use's of the interval being allocated to make it possible for the interval to target a register and spill it right away and restore a register for uses. This likely generates terrible code but is before than aborting.
