Remove the frame size argument from function_prologue/epilogue
Later patches will add support for frame sizes that are a run-time
invariant but not a compile-time constant. This then raised the
question of whether the frame size argument to the function_prologue/
epilogue hooks should be updated accordingly.
It turned out that only two targets actually used this argument, and
even they got other frame-related information from the cached machine
structure. This patch therefore removes the argument and makes the two
targets use get_frame_size () instead.
