I noticed this while working on other MINMAX optimizations. It was
hard to find a simplified testcase though because it was dependent on
the ssa name versions. Adding the `:c` to cmp allows the pattern to
be match for the case where minmax as the first operand of the comparison
rather than the second.
Committed as obvious after a bootstrap/test on x86_64-linux-gnu.
