PR tree-optimization/24964
* simplify-rtx.c (simplify_binary_operation_1): Add function comment.
<MULT>: Minor clean-up. Don't convert x*-1.0 into -x if we honor
signaling NaNs. Optimize -x*-x as x*x for all float modes, and
abs(x)*abs(x) as x*x for scalar floating point modes.
* gcc.target/i386/387-10.c: New test case.
