Nit: better to use "true" rather than "TRUE" in m
z13 supports only non-signaling vector comparisons. This means we
cannot vectorize LT, LE, GT, GE and LTGT when compiling for z13.
However, we cannot express this restriction today: the code only checks
whether vcond$a$b optab exists, which does not contain information about
the operation.
