Fix call stack sampling for the case when native callback invokes JS function
...
The SafeStackFrameIterator used by CPU profiler checked if Isolate::c_entry_fp is null and if it is not it would think that the control flow currently is in some native code. This assumption is wrong because the native code could have called a JS function but JSEntryStub would not reset c_entry_fp to NULL in that case. This CL adds a check in SafeStackFrameIterator::IsValidTop for the case when there is a JAVA_SCRIPT frame on top of EXIT frame.
Also this CL changes ExternalCallbackScope behavior to provide access to the whole stack of the scope objects instead of only top one. This allowed to provide exact callback names for those EXIT frames where external callbacks are called. Without this change it was possible only for the top most native call.

The idea is to extract all the CodeEvent loggers into separate classes
make an interface for code events and put them into a listeners array.
I extracted code that works with name_buffer into a separate base class CodeEventLogger.
And made JitLogger, LowLevelLogger and new CodeMap its descendants.
As a side effect I converted NameBuffer into nested class of CodeEventLogger
and converted NameMap into nested class of CodeMap.

Fix unaligned accesses in back_edge tables.
...
This patch fixes the step size of masm->pc_ in back_edge tables to words (4 bytes) to ensure 4 bytes alignment for read/write operations. Read and write of words (4 bytes) data from aligned space (address % 4 == 0) is more efficient on all platforms and especially on MIPS where without this alignment fix a kernel exception handler is used for every unaligned access.
This patch increases the size of back_edge tables by 3 bytes in every row. By the test it seem the back_edge table quite small in every/most cases (maximal length is 18 so in that case there are only 54 additional bytes with this patch).

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:

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.

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.

Fix invalid array length check in TransitionElementsKindStub.
...
The stub used to check the length of the JS array to see if
there's a need to duplicate the elements backing store. This
way it will not duplicate the elements array when going from
double to object even if the elements array is not the empty
fixed array. Later on it will then store pointers into a
FixedDoubleArray.
The native code stub used to check whether elements points to
the empty_fixed_array singleton instead of testing the length.
The Hydrogen stub does that as well now.

[Object.observe] Lazily allocate callbackInfo structure
...
This patch allows callbacks to lazily allocate the InternalArray which is used to store pendingChangeRecords. This moves some of the expense of observation to the case where changes actually occurred.
When there are no pendingChangeRecords, the callbackInfo structure is a number which is the callbacks priority. Whenever a changeRecord is enqueued to the callback, it "normalizes" to be an InternalArray with a priority property. Immediately before its changeRecords are delivered, it returns to its optimized state.
---
Note: Naming confusion resolved:
This patch corrects some naming confusion in object-observe.js. Previously, we used the terms "callback" and "observer" to mean roughly the same thing, and overloaded the term "observer" to be both the callback itself and the *registration* on a object to observe (which now includes an accept map).
This patch resolves this confusion:
"object" (objectInfo, objectInfoMap): This refers to the observed object and its structures
"callback" (callbackInfo, callbackInfoMap): This refers to the callback to whom change records may be delivered
"observer" (objectInfo.changeObservers): This refers to a registration to observe a given object by a given callback with the specified accept list.

Don't use StoreIC_ArrayLength on frozen arrays

The code previously assumed that an array with fast properties must have

simply adds a !is_frozen check to the IC code. Any future optimizations
to attribute-setting on JSArrays will need to make similar accomodations.
