You can register lli as an interpreter for files with magic of "llvm" using the
binfmt_misc module in the linux kernel:

[root at ice:fs]$ mount -t binfmt_misc none /proc/sys/fs/binfmt_misc
[root at ice:binfmt_misc]$ echo ':llvm:M::llvm::/path/to/lli:' >
/proc/sys/fs/binfmt_misc/register

Then you don't need the shell script wrapper. :)

[jack at ice:c]$ cat hello.c 
#include <stdio.h>
int main() {
        printf("hello world\n");
        return 0;
}
[jack at ice:c]$ llvmgcc -o hello hello.c
[jack at ice:c]$ ./hello.bc 
hello world
