f9b93e6cc7 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.

4a7c70de23 Add zapping of Map contents in debug mode. 
This zaps the contents of stale descriptor arrays and prototype
transition arrays before overwriting references to them. It should help
to discover accidental sharing early and is needed for the heap verifier
when map collection with incremental marking lands.

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.

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

a5a5f26ebb MIPS: Fix register clobbering in LoadIC for interceptors. 
Port r11492 (d14ada19)

Original commit message:
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.

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

93113da5a2 Eliminate redundant array bound checks (checks already performed earlier in the DT). 
As a special case, for checks on index expressions with the form (expr + constant) if a smaller constant is checked later in the DT also eliminate the check.
Finally, if a larger constant is checked later in the same BB do the more general check (larger constant) earlier instead of the less general one.
This will not cause useless deoptimizations because, since we are in the same BB, all the checks would have been executed anyway.

7d22d73ebf Fix issues when stressing compaction with WeakMaps. 
1) While marking the backing hash table of a WeakMap we also need to
   record the slot because it might be on an evacuation candidate.
2) With incremental marking one backing hash table might be marked more
   than once because the WeakMap might have gone through a white to gray
   transition.
3) The corner case when the allocation of the backing hash table itself
   causes a GC, leads to a WeakMap with an undefined table field, so we
   still need to handle this case correctly.

73814e7500 Fixed type transitions for mod on ia32. 
Previously we got stuck in the int32 state, because this handled everything
without a type transition. Note that other platforms do not have this bug.

977b602727 MIPS: Implement rudimentary module linking. 
Port r11336 (6dd4e844)

Original commit message:

Implement rudimentary module linking.

Constructs the (generally cyclic) graph of module instance objects
and populates their exports. Any exports other than nested modules
are currently set to 'undefined' (but already present as properties).

Details:
- Added new type JSModule for instance objects: a JSObject carrying a context.
- Statically allocate instance objects for all module literals (in parser 8-}).
- Extend interfaces to record and unify concrete instance objects,
and to support iteration over members.
- Introduce new runtime function for pushing module contexts.
- Generate code for allocating, initializing, and setting module contexts,
and for populating instance objects from module literals.
Currently, all non-module exports are still initialized with 'undefined'.
- Module aliases are resolved statically, so no special code is required.
- Make sure that code containing module constructs is never optimized
(macrofy AST node construction flag setting while we're at it).
- Add test case checking linkage.

62945585fd Implement ES5 erratum: global declarations shadow inherited properties. 
I also discovered that our treatment of const declarations is inconsistent
when inside a global eval under 'with' (i.e., when created by
DeclareContextSlots). That is,

  var x;
  eval("const x = 9")

and

  var x;
  eval("with({}) const x = 9")

differ (the former assigns 9, the latter throws). This appears to be an
oversight from earlier changes to our const semantics (the latter shouldn't
throw either). Fixing this is a separate issue, though (and one that doesn't
seem quite worthwhile).

267879e92c Fix fast API call for MinGW-w64 
MinGW-w64 uses the rcx register for the first argument. Unlike MSVC, it does not require preparing a slot for the result handle on the stack and putting a pointer to it in the rcx register.

f07b21337b MIPS: Add isolate accessor to AccessorInfo and Arguments. 
Port r11306 (36b58f7).

Original commit message:

This passes the isolate through to API callback functions so that it is
available through AccessorInfo and Arguments. This allows bindings to
avoid unnecessary TLS lookups to retrieve the current isolate.

037785baaa MIPS: Improve performance of keyed loads/stores which have a HeapNumber index. 
Port r11282 (bd2ab07).

Patch by Daniel Kalmar.

Original commit message:

Some GWT compiled code results in array access that has a heap number (e.g. -0)
as an index. Until now this would result in a generic IC.

For example:

a[-0] === a[0] or

a[0.25 * 4] === a[1]

This change detects heap numbers that are representable as a smi
and converts them. As a result we can still use the fast keyed monomorphic
ICs. Optimized code already handles keyed access with a double-key efficiently.

As a result the frame rate on the reported benchmark improves by roughly 2x.

436098b4a2 Prepare DefinePropertyAccessor for callback transitions. 
Although things are currently OK here, in the future it won't be enough to check
for the existence of a CALLBACKS result, we must additionally check that it
actually contains an accessor. In a nutshell: 'sed s/IsFound/IsProperty/' once
again...

Additionally, the control flow in DefinePropertyAccessor has been simplified by
using a helper function.

18a24a5882 MIPS: Increase external array allocation header size to 8 bytes. 
This fixes alignment issues on MIPS HW, found for example in mjsunit external-array.
The issue originates from r11144 (86563c3e21) which adds a 4-byte header to these arrays.
This causes problems on MIPS, where certain pointers need to be 8-byte aligned.
