This patch adds the LoongArch64 support for GCC D frontend. The runtime support is submitted as a separate patch here: https://github.com/dlang/dmd/pull/15628.
You can find more information about the LoongArch architecture on this website: https://loongson.github.io/LoongArch-Documentation/README-EN.html. ------ Changes since the last revision of the patch: * Corrected copyright years in loongarch-d.cc and loongarch-d.h. * Removed changes to the tests, the changes have been rolled into the DMD changes in: https://github.com/dlang/dmd/pull/15628/commits/eb84b8a2bc86aa751ad6f472422e8abad63ff500 . * Removed D_LP32 and D_LP64 bits. Since LoongArch ABIs are somewhat complicated, we may introduce the ABI information in the form of target traits in the future.
