of code stubs are too complex to be described this way, and they are encoded with the macro DEFINE_NULL_CALL_INTERFACE_DESCRIPTOR(). Along the way: * allowed inheritance of CallInterfaceDescriptors. * Defined static Register methods for some of the new CallInterfaceDescriptors. We could go a lot further here, but it doesn't have to be done immediately. * Added Representation arrays to some CallInterfaceDescriptors, especially where future hydrogen versions of the stubs could benefit from this knowledge.

When FLAG_vector_ics is true, then AST nodes that use Load and KeyedLoad ICs will allocate a type vector slot to store feedback information. Full codegen will emit a load of the slot into a register if the flag is on. Support is incomplete, right now the IC doesn't know how to use the feedback slot.

StubCallInterfaceDescriptor and CallInterfaceDescriptor are unified under a base class InterfaceDescriptor. Handling of the context register had to be massaged to effect the unification.

This is a mostly mechanical CL (more than 90% Emacs macros and query-replace-regexp) moving FILE*/StringStream*-based APIs to OStream-based APIs. There are a few places where this had to stop, otherwise the CL would be even bigger, but this can easily and incrementally cleaned up later.

Avoid generating duplicate vmla instructions for vmul/vadd sequences where the vmul has more than one use. For example: function f(a, b, c) { return (a * b) + c + (a * b); } Previously, this would produce a vmul for the subexpression (a * b), then vmla for (a * b) + c, then vmla for (a * b) + [(a * b) + c]. Now it produces vmul, vadd, vadd, as expected.
