[PATCH][AARCH64] Add testcases for TLS relocations

[Sofiane Naci]

Hi,

This patch adds testcases for the TLS relocations:

  R_AARCH64_TLSLE_MOVW_TPREL_G2
  R_AARCH64_TLSLE_MOVW_TPREL_G1
  R_AARCH64_TLSLE_MOVW_TPREL_G1_NC

and adds a sanity check in gas to ensure R_AARCH64_TLSLE_MOVW_TPREL_G*_NC
relocations are correctly used with MOVK instructions.

Thanks
Sofiane
