clang (inline-asm): assertion `NumBits >= MIN_INT_BITS && "bitwidth too small"' failed.

Extended Description
Actually, I am not sure how important such assertion failure/segment faults caused by invalid inline-asm are. It may not be that important as other cases. So I will mark all my inline-asm-relevant bugs as enhancement.
Following code trigger an assertion failure on 11.0, 12.0, and trunk.
$ cat /tmp/test-845692.c
# 1 "<built-in>"
# 1 "test.c"
int a[];
int main() {
asm("xor %%eax, %%eax;\n"
"mov %%eax, %0;\n"
: "=r"(a));
}
$ cat /tmp/test-845692.sh
