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.
