19cf3a3685 Factor out division by squares 
This patch implements the some of the division optimizations discussed in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71026.

The division reciprocal optimization now handles divisions by squares:

     x / (y * y) -> x  * (1 / y) * (1 / y)

This requires at least one more division by y before it triggers - the
3 divisions of (1/ y) are then CSEd into a single division.  Overall
this changes 1 division into 1 multiply, which is generally much faster.
