* config/mips/mips-protos.h (mips16_gp_pseudo_reg): Remove.

	* config/mips/mips-protos.h (mips16_gp_pseudo_reg): Remove.
	* config/mips/mips.h (LEGITIMATE_CONSTANT_P): Remove orphaned comment.
	* config/mips/mips.c (mips_reloc_offset_ok_p): New function.
	(mips_classify_constant): Use it.
	(mips_splittable_symbol_p): Add an offset argument.
	(mips_classify_address): Adjust call accordingly.
	(mips_legitimize_symbol): Handle sdata references with LO_SUM rather
	than a relocation unspec.  Update call to mips_splittable_symbol_p.
	Generalize the code that copes with symbols + invalid offsets.
	(print_operand): Allow '%R' to be applied to small data addresses.
	(mips_reloc_string): Remove RELOC_GPREL16.
	(mips_sdata_pointer): Renamed from mips16_gp_pseudo_reg.  Return $gp
	for TARGET_EXPLICIT_RELOCS.  Return null if we can't use gp-relative
	relocation operators.
	* config/mips/mips.md (RELOC_GPREL16): Remove.  Shuffle other reloc
	constants accordingly.
