7e62715e - [RISCV,LoongArch,MC] Replace getSymA()->getSymbol() with getAddSym. NFC

[RISCV,LoongArch,MC] Replace getSymA()->getSymbol() with getAddSym. NFC We will replace the MCSymbolRefExpr member in MCValue with MCSymbol. This change reduces dependence on MCSymbolRefExpr. Creating a MCSymbolRefExpr in *AsmBackend::handleAddSubRelocations is not efficient, but it is temporary and will be replaced when MCValue no longer uses MCSymbolRefExpr.
