* elfnn-aarch64.c (IS_AARCH64_TLS_RELAX_RELOC): Add
TLSIE_MOVW_GOTTPREL_G1.
(aarch64_tls_transition_without_check): Add
TLSIE_MOVW_GOTTPREL_G1 to TLSLE_MOVW_TPREL_G2
transition for local symbol.
(elfNN_aarch64_tls_relax): Add a argument to pass tp offset.
Add TLSIE_MOVW_GOTTPREL_G1 relaxation.
(elfNN_aarch64_relocate_section): Call elfNN_aarch64_tls_relax
with new argument.
