Maybe we could check in vect_determine_min_output_precision_1
whether the result is used as a shift amount, and if so do:
precision = MAX (precision, use_stmt_info->min_output_precision);

--- Comment #2 from Richard Biener ---
"Fixed" source (MULWU), side-stepping GENERIC folding/narrowing of the
subtract:
inline uint64_t MULWU(uint64_t k, uint64_t m)
{
unsigned long xyz = BITS-m;
return (( (k)<<(m) & M61) + ( (k) >> (xyz))
