Jinyang He a8081ed8ff [LoongArch] Allow delayed decision for ADD/SUB relocations (#72960) ...

Refer to RISCV [1], LoongArch also need delayed decision for ADD/SUB
relocations. In handleAddSubRelocations, just return directly if SecA !=
SecB, handleFixup usually will finish the the rest of creating PCRel
relocations works. Otherwise we emit relocs depends on whether
relaxation is enabled. If not, we return true and avoid record ADD/SUB
relocations.
Now the two symbols separated by alignment directive will return without
folding symbol offset in AttemptToFoldSymbolOffsetDifference, which has
the same effect when relaxation is enabled.
