LoongArch: Define ISA versions

These ISA versions are defined as -march= parameters and
are recommended for building binaries for distribution.

Detailed description of these definitions can be found at
https://github.com/loongson/la-toolchain-conventions, which
the LoongArch GCC port aims to conform to.

gcc/ChangeLog:

	* config.gcc: Make la64v1.0 the default ISA preset of the lp64d ABI.
	* config/loongarch/genopts/loongarch-strings: Define la64v1.0, la64v1.1.
	* config/loongarch/genopts/loongarch.opt.in: Likewise.
	* config/loongarch/loongarch-c.cc (LARCH_CPP_SET_PROCESSOR): Likewise.
	(loongarch_cpu_cpp_builtins): Likewise.
	* config/loongarch/loongarch-cpu.cc (get_native_prid): Likewise.
	(fill_native_cpu_config): Likewise.
	* config/loongarch/loongarch-def.cc (array_tune): Likewise.
	* config/loongarch/loongarch-def.h: Likewise.
	* config/loongarch/loongarch-driver.cc (driver_set_m_parm): Likewise.
	(driver_get_normalized_m_opts): Likewise.
	* config/loongarch/loongarch-opts.cc (default_tune_for_arch): Likewise.
	(TUNE_FOR_ARCH): Likewise.

	(loongarch_target_option_override): Likewise.
	* config/loongarch/loongarch-opts.h (TARGET_uARCH_LA464): Likewise.

	(STR_ARCH_ABI_DEFAULT): Likewise.
	(STR_TUNE_GENERIC): Likewise.
	(STR_ARCH_LA64V1_0): Likewise.
	(STR_ARCH_LA64V1_1): Likewise.
