  Log Message:
  -----------
  [lld][LoongArch] Check that the relocation addend is zero before applying relaxation to R_LARCH_GOT_PC_{HI20,LO12} (#151264)

Linker relaxation to R_LARCH_GOT_PC_{HI20,LO12} is only possible when
the addend of the relocation is zero.

Note: For `ld.bfd`, GOT references with non-zero addends will trigger an
assert in LoongArch, but `lld` handles these cases without any errors.
```
ld.bfd: BFD (GNU Binutils) 2.44.0 assertion fail
/usr/src/debug/binutils/binutils-gdb/bfd/elfnn-loongarch.c:4248
```
