LoongArch: Handle ISA evolution switches along with other options

gcc/ChangeLog:

	* config/loongarch/genopts/genstr.sh: Prepend the isa_evolution
	variable with the common la_ prefix.
	* config/loongarch/genopts/loongarch.opt.in: Mark ISA evolution
	flags as saved using TargetVariable.
	* config/loongarch/loongarch.opt: Same.
	* config/loongarch/loongarch-def.h: Define evolution_set to
	mark changes to the -march default.
	* config/loongarch/loongarch-driver.cc: Same.
	* config/loongarch/loongarch-opts.cc: Same.
	* config/loongarch/loongarch-opts.h: Define and use ISA evolution
	conditions around the la_target structure.
	* config/loongarch/loongarch.cc: Same.
	* config/loongarch/loongarch.md: Same.
	* config/loongarch/loongarch-builtins.cc: Same.
	* config/loongarch/loongarch-c.cc: Same.
	* config/loongarch/lasx.md: Same.
	* config/loongarch/lsx.md: Same.
	* config/loongarch/sync.md: Same.
