Add gdbarch_in_function_epilogue_p hook for sparc64.

Browse source 
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.
