Jakob Stoklund Olesen 1dd377d8c8 Move more fragments of spill weight calculation into CalcSpillWeights.h ...

Simplify the spill weight calculation a bit by bypassing
getApproximateInstructionCount() and using LiveInterval::getSize() directly.
This changes the computed spill weights, but only by a constant factor in each
function. It should not affect how spill weights compare against each other, and
so it shouldn't affect code generation.
