always knows which isolate we're in. There's no way we can teach this
info to the C++ allocator.

This is called from Runtime, and was dropping the requested alignment
for doubles. Needed for upcoming MIPS CL to remove some more
workarounds for load/store doubles.

ES6 specifies that methods on TypedArrays reference an internal length
slot, rather than their length property. This patch tests that for the
TypedArray methods that exist currently.

If the typer was able to prove that a NumberAdd/Sub/Mul/Div/Mod always
produces a Signed32/Unsigned32 value, and the inputs are
Signed32/Unsigned32, we can lower the node to the corresponding integer
operation instead, no matter what the uses are.

original commit message:
Make the parser handle references to "this" as unresolved variables, so the
same logic as for the rest of function parameters is used for the receiver.
Minor additions to the code generation handle copying the receiver to the
context, along with the rest of the function parameters.
Based on work by Adrian Perez de Castro <aperez@igalia.com>.

This was already done for other binary operations, so it's basically
copying the existing functionality to shift left and shift right
logical/arithmetic.

HMaybeGrowElements moves the situation where you actually have to grow
into deferred code. This means crankshaft doesn't have to spill registers
just to make the bounds comparison to see if it'll need to grow or not.
It makes the growing case a bit more expensive, but reduces the cost of
the general case.

This stub will be used as the basis of a Math.floor-specific CallIC to
detect and track calls to floor that return -0.
Along the way:
- Create a TurboFanCodeStub super class from which the StringLength and
MathRound TF stubs derive.
- Fix the ugly hack that passes the first stub parameter as the "this"
pointer in the the TF-compiled JS function.
- Fix bugs in the ia32/x64 disassembler.

We keep an eye on the recursion depth. Once it exceeds a limit, we serialize
only the object header and size, but defer serializing the object body for
after we have unwound the stack.

Use these check points to optimize comparisons where we already know
that one side cannot be a String (or turn into a string via
ToPrimitive).
Also remove bunch of useless DoNotCrash tests for the scheduler that are
painful to maintain and add almost no value.

This patch adds three methods to TypedArrays which are already
implemented for arrays. The implementations are made by calling
out to the underlying code used by Arrays.

Some of the DevTools' clients need to inspect JS objects without enabling debugger. This CL allows to inspect object's internal properties without enabling debugger and instantiating debug context.
Note that now debug context can be created lazily if v8::Debug::GetDebugContext is called when there is no debug listener. This is fragile and has already resulted in some subtle error. I'm going to fix that in a separate CL.
