ec8c6f4692 Rename AllocationSiteInfo to AllocationMemento
This is just a rename change with the exception of a bug found along the way in
CodeStubGraphBuilder<FastCloneShallowArrayStub>::BuildCodeStub(). There, the
intent is to get the boilerplate object from an AllocationSite. But the wrong
HObjectAccess was used. It only succeeds because it happened to be the same
offset :).

02649f08bc Implement simple effect typing for variables
For that, we maintain an abstract store typing of all variables with LOCAL location (i.e., those that do not escape the function's own scope). We treat assignments as sequential effects that modify this store.

When control flow branches, we have to compute the disjunction of possible effects. To that end, we represent the store as a stack of effect sets, such that we can cheaply push and pop "local" effects when control flow has to branch.

In cases of non-local control transfer from an unknown source, we currently erase all knowledge about the store.

The 'switch' statement is still to come.

For a formulation of the typing rules, see:

https://docs.google.com/a/google.com/file/d/0B3wuXSv9YKuKeUNkVXZDemZ0Z1E

3761e0388d With >= 64 non-string instance types, I removed an optimization that allowed us to detect internalized strings with a single bit test. (https://code.google.com/p/v8/source/detail?r=15358) But that change caused a regression, so here is an improvement:
Put the internalized string types in the lower 64 entries of
INSTANCE_TYPE, and non-internalized string types in the next 64 entries.
This way we can restore the single bit check.

d750a6dcd8 Consistently use HStringAdd instead of HCallStub with CodeStub::StringAdd.
Previously there were two ways to actually use the StringAddStub
from Hydrogen:

- Either using HStringAdd (which implied NO_STRING_CHECK_IN_STUB
  and and does the argument handling internally),
- or using HCallStub with CodeStub::StringAdd (which implied
  NO_STRING_ADD_FLAGS and expected the arguments to be on the
  stack already).

00ed79fb8b Move FindCodeObject from Heap to Isolate.
This removes the isolate=>heap=>isolate nonsense and has the additional bonus
that it re-enables printing of code objects in GDB. NOT: To make the latter
work, one has to adapt GDB any macros using FindCodeObject! Keeping things as it
is and outlining Isolate::heap() was not really an option...

Side note: Currently we are lucky that we still have Isolate::Current()
available in GDB, although it is marked as INLINE. :-}

97681be4e5 Fix data race in SamplingCircularQueue
This change fixes data race described in the bug by adding Acquire_Load to SamplingCircularQueue::StartDequeue and Acquire_Store to SamplingCircularQueue::Enqueue.

Also the queue implementation imposed a constraint on the records it stored: the first AtomicWord in each record was a marker. For that purpose TickSampleEventRecord had filter field of type int. This approach is error prone, e.g. on x64 sizeof(AtomicWord) is 8 while sizeof(int) is 4. Moreover the queue needs such marker only at the beginning of chunk. I changed the queue so that it stores the marker explicitly as the first Cell in chunk and removed the filter field.

462f6be930 MIPS: The gc should be able to traverse all AllocationSites for decision making.
Port r15715 (2e830d4)

Original commit message:
The gc should be able to traverse all AllocationSites for decision making. The sites are threaded into a weak list. Special problems include:

* Allocations of AllocationSites occur in generated code, so generated code needs to be able to add to the list. For now I have a special hydrogen instruction, though it would be nice to use general purpose instructions.
* The snapshot contains AllocationSites, and these need to be re-threaded into the list on deserialization.

Something nice is that the AllocationSites are only created in old space, so a special new space visitor isn't required.

9ed1fe1ac4 Better fix for LiteralCompareTypeof
This reverts r15725 and replaces it with the following one-liner
in hydrogen.cc's HandleLiteralCompareTypeof:

-  CHECK_ALIVE(VisitForValue(sub_expr));
+  CHECK_ALIVE(VisitForTypeOf(sub_expr));
