[PATCH] Fix crash when using NEON array types in inline ASM

The following code causes a crash in the LLVM backend, as uint8x8x4_t is a
struct containing an array, which is not handled by the ARM backend. This
patch prevents the crash.

#include <arm_neon.h>
int main(int argc, char *argv[])
    uint8x8x4_t vsrc;

    asm volatile (
        "vld4.u8 %h[vsrc], %[src]!;"
        : [vsrc] "=w" (vsrc), [src] "+r" (argv[0])
