Note: The test failure was unrelated to the fact that it run on actual
ARM hardware, but it was failing because the test relied on undefined

Add MachineSignature, which is an encapsulation of the machine types for parameters and return values in a graph.

This utility will be used to simplify Linkage and fix representation inference
to work with graphs where parameters and return values are something other
than tagged. It will also make testing representation inference a lot
easier, since we can then exactly nail down the machine types of parameters
and returns.

This CL also adds c-signature.h, which demonstrates how to convert C function
signatures into MachineSignatures. The CSignatures will be used in tests to
make it easier and simpler to codegen tests.

Remove dependency from generic lowering on compilation info for determining strictness and builtins.

This makes the graphs compositional for inlining (i.e. we can now inline a strict function into a non-strict function, or vice versa).

1) Store strict mode as parameter in StoreNamed/StoreProperty.

All JSObjects in V8 either have a map()->constructor() field or are
JSFunctions. JSProxy::Fix, however, was not enforcing this, and
Object.observe's use of JSObject::GetCreationContext() exposed this.

Note that this is not Object.observe-specific: the API call
v8::Object::CreationContext() also would have revealed this bug.

This patch chooses Object as a reasonable constructor to put on the
newly-fixed object's map. Note that this has no effect on the "constructor"
property in JS. In doing so, I've also tightened up the code underlying
JSProxy::Fix to only support JSObject and JSFunction as possible output
types.
