In unoptimized code, use the version of the CallFunctionStub that does not

Reapply: Never use classic code generator.
...
Crankshaft is now the default on all platforms. This is the first
patch on the way to removing the classic code generator from the
system.
This time with no removal of the crankshaft flag. --nocrankshaft is
not at all the same as --always-full-compiler which I had used instead
for testing. That was what caused timeouts on the buildbots because of
repeated attempts to optimize hot functions. It makes sense to keep
the crankshaft flag in case you want to run only with the full
compiler and with no adaptive compilation.

Optimize calls to object literal properties that are initialized with a function literal.
...
This allows fast calls and inlining of functions like:
var o = {f: function() { return "foo"; }}
o.f();
Object literals that contain function literals are initially created a dictionary mode
object and only transformed to fast properties once all properties are computed and
added. This allows us to create constant function properties for functions declared
inside the object literal. Function literals inside object literals are marked for
pretenuring so that they work as contant function properties.
Object literals without functions should just function as before.

Refactor construction of switch statements so it doesn't use class

There are also a few improvements. We do not use an auxiliary list of

the same switch. We do not insert empty blocks unless necessary to
maintain edge-split form.
There is also a bug fix. The entry to a clause body is a potential
join and must have a join ID set, otherwise deoptimization within the
body can go to an unpredictable place in the unoptimized code.

ARM: Align full codegen with IA32 version
...
Use ToBooleanStub in DoTest instead of runtime call.
Try allocation in generated code in VisitRegExpLiteral.
Use TranscendentalCacheStub for sin, cos and log instead of calling runtime.
Minor "alignment" of the full codegen code across platforms.

Change the baseline compiler to match the Hydrogen graph builder.
...
The Hydrogen graph translation does not build a branch for unary negation in
an effect context, so the baseline compiler should not do so either.
