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.
