config.gcc (sparc*-*-*): Accept mcpu=leon3v7 processor. 

2014-10-24  Daniel Hellstrom  <daniel@gaisler.com>

	* config.gcc (sparc*-*-*): Accept mcpu=leon3v7 processor.
	* doc/invoke.texi (SPARC options): Add mcpu=leon3v7 comment.
	* config/sparc/leon.md (leon3_load, leon_store, leon_fp_*): Handle
	leon3v7 as leon3.
	* config/sparc/sparc-opts.h (enum processor_type): Add LEON3V7.
	* config/sparc/sparc.c (sparc_option_override): Add leon3v7 support.
	* config/sparc/sparc.h (TARGET_CPU_leon3v7): New define.
	* config/sparc/sparc.md (cpu): Add leon3v7.
	* config/sparc/sparc.opt (enum processor_type): Add leon3v7.
