Add loongarch64 support.
Loongarch is a new RISC ISA , which includes a 32-bit version and a 64-bit version, Here are some documents about Loongarch´╝Ü https://github.com/loongson/LoongArch-Documentation. The loongarch64 bridges implementation refers to mips64 bridges, and the code related to abi and asm has been modified Change-Id: I1d9cd3aadf63046c8cdecc9a64842567bfa1cecc Reviewed-on: https://gerrit.libreoffice.org/c/core/+/137486 Tested-by: Stephan Bergmann <sbergman@redhat.com> Reviewed-by: Stephan Bergmann <sbergman@redhat.com>
