[InstCombine] peek through fdiv to find a squared sqrt
A more general canonicalization between fdiv and fmul would not
handle this case because that would have to be limited by uses
to prevent 2 values from becoming 3 values:
(x/y) * (x/y) --> (x*x) / (y*y)
(But we probably should still have that limited -- but more general --
canonicalization independently of this change.)
