  v4 mainly adjusted the relaxation conditions of GD/LD/DESC:
1. It is possible to relax for undefined symbols.
2. Modified the pcaddi calculation method to calculate the
   got address of the symbol instead of the actual address of the symbol.

Lulu Cai (4):
  LoongArch: Add new relocs and macro for TLSDESC.
  LoongArch: Add support for TLSDESC in ld.
  LoongArch: Add tls transition support. Transitions between DESC->IE/LE
    and IE->LE are supported now.
  LoongArch: Add testsuit for DESC and tls transition and tls
    relaxation.

  LoongArch: TLS LD/GD/DESC relaxation
