* msp430-decode.opc: New.
* msp430-decode.c: New/generated.
	* Makefile.am (TARGET_LIBOPCODES_CFILES): Add msp430-decode.c.
	(MAINTAINER_CLEANFILES): Likewise.
	Add rule to build msp430-decode.c frommsp430decode.opc
        using the opc2c program.
	* Makefile.in: Regenerate.
	* configure.in: Add msp430-decode.lo to msp430 architecture files.
	* configure: Regenerate.
	* msp430-decode.h: New.
