microMIPS/BFD: Add missing NewABI TLS and miscellaneous relocations

Complement commit df58fc944dbc ("MIPS: microMIPS ASE support"),
<https://sourceware.org/ml/binutils/2011-07/msg00198.html>, and add TLS
and a few miscellaneous relocations to NewABI microMIPS support, fixing
GAS assertion failures:

.../gas/testsuite/gas/mips/elf-rel28.s: Assembler messages:
.../gas/testsuite/gas/mips/elf-rel28.s:19: Internal error in append_insn at .../gas/config/tc-mips.c:7660.
Please report this bug.

observed if an attempt is made to assemble the `elf-rel28.s' test case
to microMIPS code.  The relocations are the same as with o32 support,
except for `partial_inplace' and `src_mask' updates for the respective
RELA variants.

	bfd/
	* elf64-mips.c (micromips_elf64_howto_table_rel): Add
	R_MICROMIPS_HI0_LO16, R_MICROMIPS_TLS_GD, R_MICROMIPS_TLS_LDM,

	R_MICROMIPS_TLS_TPREL_LO16, R_MICROMIPS_GPREL7_S2 and
	R_MICROMIPS_PC23_S2 relocation entries.
	(micromips_elf64_howto_table_rela): Likewise.

	* elfn32-mips.c (elf_micromips_howto_table_rel): Likewise.
	(elf_micromips_howto_table_rela): Likewise.
