Avoid useless #ifdef DEBUG checks for the --trace-ic flag.

FLAG_trace_ic is constant false in non-DEBUG builds anyways.

Remove the strict-mode flag from store handlers. It's only relevant to the IC stub.

The goal is to discover the appropriate heap space for objects created in full
code. By the time we optimize the code, we'll be able to decide on new or old
space based on the number of surviving objects after one or more gcs.

The mechanism is a "memento" placed behind objects in the heap. It's currently
done for array and object literals, with plans to use mementos for constructed
objects as well (in a later CL).

The feature is behind the flag allocation_site_pretenuring, currently off.
