[hydrogen] Add crash-hunting instrumentation to Hydrogen too

[hydrogen] Add crash-hunting instrumentation to Hydrogen too

This extends instrumentation added in r30683 and r30768 to cover
the possibility that the root cause we're after is in optimized code.

This CL is intended to be reverted in a couple of days, but should
cause no harm while it's in the tree (we would crash anyway).
