	(mips16_stub_symndx): Likewise.
	(mips_elf_check_mips16_stubs): Treat the data argument as a
	bfd_link_info.  Mark every dynamic symbol as needing MIPS16 stubs
	and create a "shadow" symbol for the original MIPS16 definition.
	(mips16_reloc_p, got16_reloc_p, call16_reloc_p, hi16_reloc_p)
	(lo16_reloc_p, mips16_call_reloc_p): New functions.

	symbols into even MIPS16 symbols.

	earlier in the function.  Use mips16_stub_symndx to identify
	the target function.  Avoid out-of-bounds accesses when the
	stub has no relocations; report an error instead.  Use
	section_allows_mips16_refs_p instead of mips16_stub_section_p.
	Use mips16_call_reloc_p and got16_reloc_p to generalize relocation
	checks.  Handle R_MIPS16_CALL16 and R_MIPS16_GOT16.  Don't create
	dynamic relocations for absolute references to __gnu_local_gp.
	(_bfd_mips_elf_always_size_sections): Pass a bfd_link_info as
	the argument to mips_elf_check_mips16_stubs.  Generalize comment.
	(_bfd_mips_elf_relocate_section): Use hi16_reloc_p and got16_reloc_p
	to generalize relocation checks.
	(_bfd_mips_elf_finish_dynamic_symbol): If a dynamic MIPS16 function
	symbol has a non-MIPS16 stub, redirect the symbol to the stub.
	Fix an overly long line.  Don't give dynamic symbols type STO_MIPS16.
	(_bfd_mips_elf_gc_sweep_hook): Handle R_MIPS16_CALL16 and
	R_MIPS16_GOT16.
