MIPS: Reduce size of LIR instruction by one word and remove dead code.
...
Port r11454 (72c662fc)
Original commit message:
Reduce size of LIR instruction by one word and remove dead code.
Until now we always recorded two deoptimization environments for instructions
that are marked as calls. We actually don't need two for all LIR
instructions except one (LInstanceOfKnownGlobal) where there is a lazy
deoptimization point in deferred code.
This change remove on of them and uses one virtual function instead
to make LInstanceOfKnownGlobal work as before.
Additionally, this change removes an unused predicate save_doubles_ from LIR
instructions and removes some helper functions that are used only in one place.

Bumped bootup memory limit on 32bit platforms using snapshot.
...
Somehow the mmaps we do look the same, but the info in the proc FS tells us that
we use a bit more memory. I am not sure if this is a real issue or not, but this
CL should at least get the build bots green again...

Use map transitions when defining accessor properties.
...
AccessorPairs can now contain map transitions, which is similar to our current
handling of CONSTANT_FUNCTION/CONSTANT_TRANSITION, but generalized to a pair for
holding info about the getter and the setter. This way we can achieve map
sharing for objects with accessor properties, which is a prerequisite for making
them fast via inlining. We fall back to the previous way of handling accessor
properties when sharing is not possible or we don't handle a special case.
Note: When an exisiting accessor property is redefined we could in principle
move the AccessorPair out of the descriptor into the object itself (again just
like the way we do something similar for CONSTANT_FUNCTION/CONSTANT_TRANSITION),
but this would require a new property kind for holding a pair of values. Perhaps
we can implement this later, but for now this hopefully rare case is handled
like before, losing map sharing and potentially creating more maps than strictly
necessary.
