Avoid adding HWrapReceiver during graph building.

This adds an early check to the graph builder which prevents adding an
HWrapReceiver instruction if the receiver type is already known at graph
building time. Also HAllocate no longer unnecessarily postpones setting
it's type until type inference but sets it right away. These changes are
in preparation for escape analysis.

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.

Logger: extract CodeEventLogger classes.
...
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.

Original commit message:
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.

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.

Fixed type feedback in presence of negative lookups.
...
To fix the issue at hand regarding constant function calls and perhaps
other hidden issues regarding negative lookups, we basically add a
"marker instruction", just for harvesting purposes. Our type feedback
oracle is really, really fragile, we should better switch to some more
explicit and robust scheme soon.

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.
