Now AllocateClosureInstr takes the closure function as a Value* instead
of as a const Function&, a new kFunctionReg is added to
AllocateClosureABI, and the AllocateClosure stub sets the closure
function internally instead of initializing it to null and requiring it
to be set post-allocation.
A convenience method known_function() is added to AllocateClosureInstr
which returns either the closure function, if known at compile time,
or null otherwise.
TEST=More refactorings, so just passing current tests.
