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>.

original commit message:

    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.

Also remove bunch of useless DoNotCrash tests for the scheduler that are

This patch adds the copyWithin method to TypedArrays. For the first
pass, the internals of Array.copyWithin are used. Eventually, a more
efficient form based on memcpy could be used instead.
