Remove the "bad idea" of spilling whenever there's a deopt, and instead
use the deoptimizer's register support.

In addition, allow untagged int32 inputs into deopts -- if tagging these
overflows, then the deoptimizer will automagically create a HeapNumber
for us. Hooray for code reuse!

Drive-bys:
    1. Print input locations for deopt checkpoints.
    2. Fix ordering of UpdateUse(input)/UpdateUse(deopt) to match the
       use marker.
