* gc.c (stack_end_address): new function to obtain stack end address.
stack_end_address calls __builtin_frame_address(0) to obtain the
frame pointer of a stack frame of stack_end_address. The address
is the stack pointer of the caller's stack frame.
(SET_STACK_END): use stack_end_address.
This makes the conservative garbage collector to scan a stack frame
of the garbage_collect function itself. This is required because
callee-save registers may be stored in the frame.
