  Remove "_NC" suffix and semantics from TLSDESC_LD{64,32}_LO12 and
    TLSDESC_LD{64,32}_ADD12 relocations
  Rearrange ordering in AArch64.def to following relocation encoding
  Fix name from R_AARCH64_P32_LD64_GOT_LO12_NC to
     R_AARCH64_P32_LD64_GOT_LO12_NC
  Add support for several "TLS", "TLSGD", and "TLSLD" relocations for
    ILP32
  Fix return values from isNonILP32reloc
  Add support for
    R_AARCH64_ADR_PREL_PG_HI21_NC, R_AARCH64_P32_LD32_GOT_LO12_NC,
    R_AARCH64_P32_TLSIE_LD32_GOTTPREL_LO12_NC,
    R_AARCH64_P32_TLSDESC_LD32_LO12, R_AARCH64_LD64_GOT_LO12_NC,
    *TLSLD_LDST128_DTPREL_LO12, *TLSLD_LDST128_DTPREL_LO12_NC,
    *TLSLE_LDST128_TPREL_LO12, *TLSLE_LDST128_TPREL_LO12_NC
  Modify error messages to give name of equivalent relocation in the
    ABI not being used, along with better checking for non-existent
    requested relocations.
  Added assembler support for "pg_hi21_nc", but not for output.
