Running with -fsanitize=undefined I get:
pr70354.c:25:30: runtime error: left shift of negative value
-1725558902283030715
pr70354.c:25:19: runtime error: shift exponent 1729382256910270464 is too large
for 64-bit type 'long int'

In scalar code we use the lowest byte as a shift operand producing some
non-zero value. In vector code it behaves differently and produces 0.
Invalid then?
