match.pd: Simplify (t * u) / (t * v) [PR112994]
On top of the previously posted patch, this simplifies say (x * 16) / (x * 4)
into 4. Unlike the previous pattern, this is something we didn't fold
previously on GENERIC, so I think it shouldn't be all wrapped with #if
GIMPLE. The question whether there should be fold_overflow_warning for the
TYPE_OVERFLOW_UNDEFINED case remains.
