d: vector float comparison doesn't result in 0 or -1 [PR108945]
When comparing two vectors, the type of vector was used as the result of
the condition result. This meant that for floating point comparisons,
each value would either be `0.0' or `-1.0' reinterpreted as an integer,
not the expected integral bitmask values `0' and `-1'.
Instead, use the comparison type determined by truth_type_for as the
result of the comparison. If a reinterpret is later required by the
final conversion for generating CmpExp, it is still only going to
reinterpret one integer kind as another.
