[PATCH] Multiarch FRAME_INIT_SAVED_REGS for mips

[Kevin Buettner <kevinb at redhat dot com>]

I've just committed the patch below.

	* mips-tdep.c (mips_find_saved_regs): Make static.
	(mips_frame_init_saved_regs): New function.
	(mips_gdbarch_init): Setup FRAME_INIT_SAVED_REGS method.
	* config/mips/tm-mips.h (FRAME_INIT_SAVED_REGS): Delete macro.
	(mips_find_saved_regs): Delete declaration.
