With the initial support added, clang can compile `helloworld` C
to executable file for loongarch64. For example:
```
$ cat hello.c
int main() {
printf("Hello, world!\n");
return 0;
}
$ clang --target=loongarch64-unknown-linux-gnu --gcc-toolchain=xxx --sysroot=xxx hello.c
```
The output a.out can run within qemu or native machine. For example:
```
$ file ./a.out
./a.out: ELF 64-bit LSB pie executable, LoongArch, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-loongarch-lp64d.so.1, for GNU/Linux 5.19.0, with debug_info, not stripped
$ ./a.out
Hello, world!
```
Currently gcc toolchain and sysroot can be found here:

The last commit hash (main branch) is:

Note loongarch32 is not fully tested because there is no reference
gcc toolchain yet.
