[Bug inline-asm/33600] New: Breakage caused by the fix to PR33552

[segher at kernel dot crashing dot org]

The fix to PR33552 unfortunately breaks the Linux kernel build.
Reduced testcase attached, but hey, I'll put it inline as well:

int f(int n)
{
        int x;

        asm("" : "=&c"(n), "=r"(x) : "1"(n), "0"(n));

        return n;
}

And the error is:
usercopy.i:5: error: 'asm' operand has impossible constraints
