Since 1e-1000 == 0.0 (on an IEEE-754 platform anyway), I would expect
-1e-1000 to be -0.0.  But it does not appear that way:

>>> 1e-1000
0.0
>>> -0.0
-0.0
>>> -1e-1000
0.0

However (correctly):

>>> (-1.0) * 1e-1000
-0.0
>>> -(1e-1000)
-0.0

I suspect the optimization for -x where x is a float literal is
incorrectly triggering here.
