Fix tree-optimization/103257: Missed jump threading due too early conversion of bool*A into bool?A:0
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.

gcc/ChangeLog:
* match.pd
((m1 >/</>=/<= m2) * d -> (m1 >/</>=/<= m2) ? d : 0):
Disable until !canonicalize_math_p ().
gcc/testsuite/ChangeLog:
* gcc.dg/tree-ssa/vrp116.c: Check optimized instead of vrp1.
* gcc.dg/tree-ssa/pr103257-1.c: New test.
