Subject: [PATCH 106/188] 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.
