* config/tc-mips.c (md_begin): If -64, create a .MIPS.options 

section rather than a .reginfo section.
	(mips_elf_final_processing): If -64, write out 64 bit RegInfo
	information.

(mips_elf_final_processing): If -64, write out 64 bit RegInfo
information.
* config/tc-mips.c (load_register): If mips_isa < 3, permit a 32
bit value with the high bit set.
