I wrote `sanitizer_syscall_linux_loongarch64.inc` and tested it with GCC.  GCC 
supports register variable definition like `register u64 a0 asm("a0");` but 
does not support `addi.d a0, a0, a1` (because in GCC such a line in inline 
assembly is passed to GNU as directly).

Is it possible to "emulate" the behavior in Clang?
