Add gdbarch_in_function_epilogue_p hook for sparc64.
watchpoint_update and watchpoint_cond avoid checking for
watchpoints when we are located at a function epilogue in the
current frame. This is done in order to avoid using corrupted
local registers and unwinding a corrupted/destroyed stack.
The code determining whether we are in a function epilogue is
provided by the backends via the gdbarch_in_function_epilogue_p
hook. This commit adds such a hook for sparc64 targets.
