src/objects.h:4729: class DependentCodes {
I could make this a proper object that derives from FixedArray, but that
seems to be an overkill. WDYT?
Description:
Make embedded maps in optimized code weak.
Each map has a weak array of dependent codes, where the map tracks all the
optimized codes that embed it.
Old space GC either clears the dead dependent codes from the array if the
corresponding map is alive or deoptimizes the live dependent codes if the
map is
dead.
