Formalize the notion that AVX and SSE are non-overlapping extensions from the compiler's point of view.

IntervalMap iterators are heavyweight, so avoid copying them around and use
...
references instead.
Similarly, IntervalMap::begin() is almost as expensive as find(), so use find(x)
instead of begin().advanceTo(x);
This makes RegAllocBasic run another 5% faster.

The BLX instruction is encoded differently than the BL, because why not? In

particular, the immediate has 20-bits of value instead of 21. And bit 0 is '0'

invariant.

Store (priority,regnum) pairs in the priority queue instead of providing an
...
abstract priority queue interface in subclasses that want to override the
priority calculations.
Subclasses must provide a getPriority() implementation instead.
This approach requires less code as long as priorities are expressable as simple
floats, and it avoids the dangers of defining potentially expensive priority
comparison functions.
It also should speed up priority_queue operations since they no longer have to
chase pointers when comparing registers. This is not measurable, though.
Preferably, we shouldn't use floats to guide code generation. The use of floats
here is derived from the use of floats for spill weights. Spill weights have a
dynamic range that doesn't lend itself easily to a fixpoint implementation.
When someone invents a stable spill weight representation, it can be reused for
allocation priorities.
