re PR tree-optimization/86835 (Bogus "is used uninitialized" warning with -ffast-math)

PR tree-optimization/86835
* tree-ssa-math-opts.c (insert_reciprocals): Even when inserting
new_stmt after def_gsi, make sure to insert new_square_stmt after
that stmt, not 2 stmts before it.

* gcc.dg/pr86835.c: New test.
