This reverts commit daa224d4.

Reason for revert: https://bugs.chromium.org/p/chromium/issues/detail?id=819873

Original change's description:
> [builtins] Remove CheckOptimizationMarker builtin
> 
> This was a shim for the non-I+TF codepath, which is now the only
> codepath (that still uses this tier-up mechanism anyway). There were a
> couple of places we were accidentally using it due to CompileLazy or
> deopts, so this also fixes those.
