* elf32-mips.c (mips_elf_next_relocation): Rename from
	mips_elf_next_lo16_relocation, and generalize to look
	for any relocation type.
	(elf_mips_howto_table): Make R_MIPS_PC16 pcrel_offset.
	(elf_mips_gnu_rel_hi16): Howto for R_MIPS_GNU_REL_HI16.
	(elf_mips_gnu_rel_lo16): Howto for R_MIPS_GNU_REL_LO16.
	(elf_mips_gnu_rel16_s2): Howto for R_MIPS_GNU_REL16_S2.
	(elf_mips_gnu_pcrel64): Howto for R_MIPS_PC64.
	(elf_mips_gnu_pcrel32): Howto for R_MIPS_PC32.
	(bfd_elf32_bfd_reloc_type_lookup): Add new relocs.
	(mips_rtype_to_howto): Likewise.
	(mips_elf_calculate_relocation): Handle new relocs.
	(_bfd_mips_elf_relocate_section): REL_HI16/REL_LO16 relocs
	are paired.  The addend for R_MIPS_GNU_REL16_S2
	is shifted right two bits.
In gas/:
	* config/tc-mips.c (mips_ip): Don't put stuff in .rodata
	when embedded-pic.

	* config/tc-mips.c (SWITCH_TABLE): The ELF embedded-pic
 	implementation doesn't have special handling for switch
 	statements.
	(macro_build): Allow for code in sections other than .text.
	(macro): Likewise.
	(mips_ip): Likewise.
	(md_apply_fix): Do pc-relative relocation madness for MIPS ELF.
  	Don't perform relocs if we will be outputting them.
	(tc_gen_reloc): For ELF, just use fx_addnumber for pc-relative
 	relocations.  Allow BFD_RELOC_16_PCREL_S2 relocs when
 	embedded-pic.
In gas/testsuite/:
	* gas/mips/empic.d: New file.
	* gas/mips/empic.s: New file.
	* gas/mips/mips16-e.d: New file.
	* gas/mips/mips16-e.s: New file.
	* gas/mips/mips16-f.d: New file.
	* gas/mips/mips16-f.s: New file.
	* gas/mips/mips.exp: Add empic, mips16-e.  Add mips16-f as an
	expected failure.
In include/elf:
	* mips.h: Add R_MIPS_GNU_REL_HI16, R_MIPS_GNU_REL_LO16,
 	R_MIPS_GNU_REL16_S2, R_MIPS_PC64 and R_MIPS_PC32 relocation
 	numbers.
