7eb7141fc4 [mjsunit] Import test case based on the Massive/SQLite benchmark. 
This adds a stripped down version of the SQLite benchmark (running with
--size 1) to the mjsunit suite. We might want to move that to a
dedicated slow/stress/whatever test suite once an appropriate decision
is made.

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.

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.
