29c48e1076 Make DeltaBlue performance more stable by ignoring type feedback that 
tells us that a map can transition to another map when we are generating
code for load operations.  This may cause us to deopt if the same routine
is seeing different maps caused by branching in constructors.  If so, I
have a different change that is around 100 times more complicated that
lets us generated Crankshaft code for negative lookups.

e443c69b8d 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.

065cc14449 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.

baf7ebd6da Fix assert triggered in fast/regex/pcre-test-4.html We were not filtering out 
all the nodes that had non-ASCII characters.  That has been fixed, but because
of the protection against over-deep recursion when filtering it is wrong to
assert that all nodes were filtered.  This change therefore also makes sure we
can cope with non-filtered nodes by adding back some code removed in

292e007cf3 Remove more assumptions from debug tests. Even though a function 
is optimized, does not mean all frames on the stack are optimized.
Also, when we ask for the list of scripts we may get more or less
depending on GC timing.  Also fixed a presubmit error and made
%GetOptimizationStatus a little more honest.

f46906d7a8 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.
