LoongArch: Support split symbol.

Add compilation option '-mexplicit-relocs', and if enable '-mexplicit-relocs'
the symbolic address load instruction 'la.*' will be split into two instructions.
This compilation option enabled by default.

gcc/ChangeLog:

	* common/config/loongarch/loongarch-common.cc:
	Enable '-fsection-anchors' when O1 and more advanced optimization.
	* config/loongarch/genopts/loongarch.opt.in: Add new option
	'-mexplicit-relocs', and enable by default.
