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.

Port r13454 (2c0dd0ff)
Original commit message:
HCheckPrototypeMaps currently records the prototype and the holder of the
prototype chain (both ends of the chain) and assumes that the chain elements
and their maps did not change in during the entirety of Crankshaft. The actual
traversal of the prototype chain happens in Lithium at code generation.
With parallel compilation, this assumption is not longer correct.

Make HCheckPrototypeMaps compatible with parallel recompilation.
...
HCheckPrototypeMaps currently records the prototype and the holder of the
prototype chain (both ends of the chain) and assumes that the chain elements
and their maps did not change in during the entirety of Crankshaft. The actual
traversal of the prototype chain happens in Lithium at code generation.
With parallel compilation, this assumption is not longer correct.
