So like many optimizations on the gimple level, sometimes it makes sense to do
the
optimization early or later. In this case, creating a cond expression early
causes
other optimizations to be missed. So just disable it until canonicalize_math_p
()
is false.
OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.
