[1/2][GAS][AARCH64]Add BFD_RELOC_AARCH64_TLSLE_LDST8/16/32/64_TPREL_LO12 support in GAS

[Renlin Li]

Hi all,

This is the first patch to add the following relocation support into binutils.
BFD_RELOC_AARCH64_TLSLE_LDST16_TPREL_LO12,
BFD_RELOC_AARCH64_TLSLE_LDST16_TPREL_LO12_NC,
BFD_RELOC_AARCH64_TLSLE_LDST32_TPREL_LO12,
BFD_RELOC_AARCH64_TLSLE_LDST32_TPREL_LO12_NC,
BFD_RELOC_AARCH64_TLSLE_LDST64_TPREL_LO12,
BFD_RELOC_AARCH64_TLSLE_LDST64_TPREL_LO12_NC,
BFD_RELOC_AARCH64_TLSLE_LDST8_TPREL_LO12,
BFD_RELOC_AARCH64_TLSLE_LDST8_TPREL_LO12_NC.

Those relocations includes both ip64 and ilp32 variant.

Regard,
Renlin
