Commit Message

Fix FOLD rule for x-0.

Reported by XmiliaH.

(cherry-picked from commit 7b994e0ee)

Fold optimization x - (-0) ==> x is INVALID for x = -0 in FP arithmetic.
Its result is -0 instead of +0. This patch allows only x - (+0) ==> x
optimization.

Sergey Kaplun:
* added the description and the test for the problem
