Adds SIMD 128 alignment sizes and masks.
Adds support in Heap for SIMD alignments and fills.
Reworks cctest so that each test independently aligns its allocation address, rather than depending on the previous tests ending state. Adds test cases for SIMD.

Embed constant pools within their corresponding Code
objects.

This removes support for out-of-line constant pools in favor
of the new approach -- the main advantage being that it
eliminates the need to allocate and manage separate constant
pool array objects.

Currently supported on PPC and ARM.  Enabled by default on
PPC only.

This yields a 6% improvment in Octane on PPC64.

This splits the SuperReference AST node into SuperPropertyReference and
SuperCallReference. The super call reference node consists of three
unresolved vars to this, new.target and this_function. These gets
declared when the right function is entered and if it is in use. The
variables gets assigned in FullCodeGenerator::Generate.

original commit message:

    [turbofan] First step towards sanitizing for-in and making it optimizable.

    In a nutshell: The FILTER_KEY builtin is gone, and was replaced by a
    simple runtime call to ForInFilter, which does everything and is even
    cheaper (because FILTER_KEY used to call into the runtime anyway).
    And ForInFilter returns either the name or undefined, which makes it
    possible to remove the control flow construction from the AstGraphBuilder,
    and thereby make both the initialization and the per-loop code of for-in
    optimizable later (in typed lowering).

Unfortunately StringAdd is not pure in V8 because we might throw an
exception if the resulting string length is outside the valid bounds, so
there's no point in having a simplified StringAdd operator.

The Map and Set maps get overwritten when collection.js executes, so in
a nosnap build we have to wait until it runs before we grab the maps.
To facilitate that, store the functions in the native context as well.
