Sven van Haastregt 5d03080092 [TargetLowering] Add i1 condition for bit comparison fold ...

For i1 types, boolean false is represented identically regardless of
the boolean content, so we can allow optimizations that otherwise
would not be correct for booleans with false represented as a negative
one.
