This removes tons of architecture-specific code and makes it easy to
experiment with other pseudo-RNG algorithms. The crankshafted code is
extremely good, keeping all things unboxed and doing only minimal
checks, so it is basically equivalent to the handwritten code.

When benchmarks are run without parallel recompilation, we get a few
percent regression on SunSpider's string-validate-input and
string-base64, but these benchmarks run so fast that the overall
SunSpider score is hardly affected and within the usual jitter. Note
that these benchmarks actually run even faster when we don't
crankshaft at all on the main thread (the regression is not caused by
bad code, it is caused by Crankshaft needing a few hundred microsecond
for compilation of a trivial function). Luckily, when parallel
recompilation is enabled, i.e. in the browser, we see no regression at
all!

This will allow for using gin and blink bindings in the same

Over r17907, I changed the order of fields in Isolate to be stable across different platforms, since the ABI defined packing is not the same on
all targets, and I initialize the embedder data field in Isolate.

A problem arises in recursive literal expressions due to recent
changes that defer allocation of constant literal properties
from parse time. We were calculating expression depth as a
side-effect of a lazy constant property build, but subsequent
calls for the depth always returned 1. Cache the correct depth
in the MaterializedLiteral instead.

If we know that one side of a string add is definitely a string
(i.e. if it's a string constant), then we don't need to emit a
string check for the argument.

This adds a new BuildCheckString() method to the graph builder,
which does "the right thing".
