    LoongArch: Simplify -mexplicit-reloc definitions
    
    Since we do not need printing or manual parsing of this option,
    (whether in the driver or for target attributes to be supported later)
    it can be handled in the .opt file framework.
    
    gcc/ChangeLog:
    
            * config/loongarch/genopts/loongarch-strings: Remove explicit-reloc
            argument string definitions.
            * config/loongarch/loongarch-str.h: Same.
            * config/loongarch/genopts/loongarch.opt.in: Mark -m[no-]explicit-relocs
            as aliases to -mexplicit-relocs={always,none}
            * config/loongarch/loongarch.opt: Regenerate.
            * config/loongarch/loongarch.cc: Same.
