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.

MIPS: Avoid handle dereference during graph optimization.
...
Port r13475 (0076e1ee)
Original commit message:
With parallel recompilation enabled, objects made accessible by handles may
have changed between graph construction and graph optimization. Therefore
we must not assume that information on those objects remain the same between
those two phases. To police this, we forbid handle dereferencing during
graph optimization.
Exceptions to this rule are:
- Dereferencing the handle to obtain the raw location of the object. This
is safe since parallel recompilation acquires RelocationLock
- Some places that dereference the handle for a type check. These are checked
to be safe on a case-by-case basis.
