[cleanup] Drop FLAG_eliminate_prototype_chain_checks

[cleanup] Drop FLAG_eliminate_prototype_chain_checks

This flag has been on by default for a while, along with
FLAG_track_prototype_users which provides the prerequisite
infrastructure. We are now sure that this is the direction
we want to go in, so in order to simplify the code, this CL
drops the respective flag-off code paths.

PTAL. If we're going to put cells into the vector, it doesn't make sense any
more to have a flag to turn off cell-based checks.
