[PATCH v4 0/4] When cmodel=extreme, add macro support and only support macros.

[Lulu Cheng <chenglulu@loongson.cn>]

v3 -> v4:
  1. Add macro support for TLS symbols
  2. Added support for loading __get_tls_addr symbol address using call36.
  3. Merge template got_load_tls_{ld/gd/le/ie}.
  4. Enable explicit reloc for extreme TLS GD/LD with -mexplicit-relocs=auto.


v2 -> v3:
  1. Modify the detection rules of a test case.

v1 -> v2:
  1. Use the temporarily allocated registers as intermediate registers to implement the extreme macro.
  2. Fixed bugs in v1 test cases.
