281d30d758 Adding V8 api to get memory statistics of spaces in V8::Heap.
This is first step towards adding V8 heap statistics to the memory
tracing infrastructure. For being able to get useful memory number into
the memory dump, v8 needs to provide an external api needs to obtain
more information about the heap. So, this Cl extends the api to give
information about the memory allocated and used in the spaces.

cc01cd94ab PPC: Array() in optimized code can create with wrong ElementsKind in corner cases.
Port 13459c1ae3

Original commit message:
Calling new Array(JSObject::kInitialMaxFastElementArray) in optimized code
makes a stub call that bails out due to the length. Currently, the bailout
code a) doesn't have the allocation site, and b) wouldn't use it if it did
because the length is perceived to be too high.

This CL passes the allocation site to the stub call (rather than undefined),
and alters the bailout code to utilize the feedback.

80f24f7a4c Reland MIPS: Vector-ICs - speed towards the monomorphic exit as quickly as possible.
Port 35a67b745d

Original commit message:
Thanks to some careful assumptions, we can examine the object found at
vector[slot] and trust it's a heap object where the second field is
either a map if it's a WeakCell, or definitely not a map if it's a
Symbol, String or FixedArray. Use this to save a memory read.

The previous restrictions were overshooting (didn't allow a class to refer to a
later class under any circumstances); after this CL we're undershooting (allow
referring to any class from inside a method).

Implementing the correct checks (allow referring only if the class declarations
are in a consecutive block and if there's no dependency cycle) will be
implemented as a follow up.

758c5e123b X87: Use Cells to check prototype chain validity (disabled by default).
port 0179ec5797 (r27846).

original commit message:

 The cells are stored on prototypes (in their map's PrototypeInfo). When a
 prototype object changes its map, then both its own validity cell and those
 of all "downsstream" prototypes are invalidated; handlers for a given receiver
 embed the currently valid cell for that receiver's prototype during their
 compilation and check it on execution.
