* config/tc-mips.c: If OBJ_ELF, include elf/mips.h. 

(mips_regmask_frag): New static variable, if OBJ_ELF.
	(md_begin): If OBJ_ELF, create .reginfo section and set
	mips_regmask_frag to a frag.
	(mips_elf_final_processing): New function, if OBJ_ELF.  Set
	mips_regmask_frag to register mask information.
	* config/tc-mips.h (elf_tc_final_processing): New macro, defined
	if OBJ_ELF.
