Clear the stack frame pointer in _start and __bionic_clone
This CL adds an instruction to the _start label that clears the frame
pointer. This allows stack walking code to determine when it has
reached the end of the stack.
The __bionic_clone function is similarly modified, for architectures
that weren't already doing both.
