0c54a2371c Implement map collection for incremental marking. 
This causes map transitions to be treated weakly during incremental
marking and hence allows clearing of non-live transitions. The marking
code is now shared between incremental and non-incremental mode.

Because heap snapshotting is now performed in a single pass
it is safe to make calls to GetConstructorName and further to
LocalLookupRealNamedProperty right within that main pass.

132af25697 Split nodes and edges into separate arrays in heap profiler. 
This allowed the following changes:
  - heap profiler now makes one pass less over the heap.
  - HeapEntriesMap does not allocate EntryInfo per each entry.
  - there's no need for an extra pass to set indexes before serialization.

As a result snapshot taking time has reduced up to 2x times.

526b3f2cac Implement explicit back pointers in transition tree. 
This makes back pointers in the map transition tree explicit by having
accurate back pointers throughout the lifetime of maps instead of
establishing and destroying back pointers before and after each marking
phase. This is a prerequisite for being able to clear map transitions
during incremental marking.

tells us that a map can transition to another map when we are generating

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.

d965561862 Fix register clobbering in LoadIC for interceptors. 
This fixes a corner-case where the receiver register was clobbered by
LoadICs for interceptors and inlined followup code still relied on the
receiver to be intact in case of prototype changes.

c810016e77 Implement clearing of CompareICs. 
This allows CompareICs to be cleared during garbage collection to avoid
cross-context garbage retention through maps stored in CompareIC stubs
for the KNOWN_OBJECTS state.

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
