This revision now requires changes to proceed.
Meta point: It's unclear to me whether this is something profitable to implement.
Sure, you can probably take a textbook and implement all the possible identities written there, but, what's the point?
I looked and it seems other compilers (most notably, GCC) don't implement at least the first transformation you implemented (I didn't bother to check the others).
tl;dr: what's your motivation?
