Pete Cooper 5a5a0640d8 Use a logical not when inverting SetCC. This unfortunately doesn't fire on any targets so I couldn't find a test case to trigger it.

The problem occurs when a non-i1 setcc is inverted.  For example 'i8 = setcc' will get 'xor 0xff' to invert this.   This is clearly wrong when the boolean contents are ZeroOrOne.

This patch introduces getLogicalNOT and updates SetCC legalisation to use it.
