Requires https://gcc.gnu.org/pipermail/gcc-patches/2023-November/636946.html. Changes: - Rebase on top of "Add LoongarchV1.1 instructions support". - Not to translate loongarch-def.c C++. Use int64_t instead of HOST_WIDE_INT in loongarch-def.h. - In genopts, also generates cpucfg_useful_idx[] and N_CPUCFG_WORDS. Use decimals instead of hexidecimals for CPUCFG word index to make awk happy to perform numerical comparision. - Dump arch and feature info as comments in generated assembly if -fverbose-asm. It's helpful for testing and debugging.
