This implements a first version of support for constructor call inlining
in the inlining machinery. For now we can only inline calls where the
actual constructor and the original constructor coincide (i.e. no super
constructor calls). Note that the target of a super constructor call is
loaded with a runtime call, so there is no way for it to be constant
promoted at the moment.

Presently the inline allocation step is a static value defined to be the minimum
of the step sizes over all the observers. The step occur every (approx.) step
byte. This is unfair to observers whose steps are not evenly divisible by the
min step size. For example, consider two observers with steps sizes of 512 and
576 bytes. Across 16kb allocated, you would expect the first observer to be hit
approximately 32 times, and the second observer to be hit approximately 28
times.

In reality, the observers get notified 30 and 15 times respectively. The reason
is that each step is 512 bytes, and since 576 is not evenly divisible by 512,
it gets notified much less frequently.

This CL fixes the problem by making the next step size be the minimum (over all
observers) of the remaining bytes to get to the step, making the steps fair.

Otherwise, back-to-back sequences which block the trampoline pool can
cause it to be out of reach.

which is actually straightforward because of the way we represent JS
