LoongArch: Adapt R_LARCH_{PCALA,GOT,TLS_IE,TLS_DESC}64_* handling per psABI v2.30
In LoongArch psABI v2.30, an offset (-8 for LO20 and -12 for HI12)
should be applied on PC for these reloc types to avoid wrong relocation
when the instruction sequence crosses a page boundary.
The lld linker has already adapted the change. Make it for the bfd
linker too.
