[PowerPC] Fix a conversion is not considered when the ISD::BR_CC node making the instruction selection
Summary:
A signed comparison of i1 values produces the opposite result to an unsigned one if the condition code
includes less-than or greater-than. This is so because 1 is the most negative signed i1 number and the
most positive unsigned i1 number. The CR-logical operations used for such comparisons are non-commutative
so for signed comparisons vs. unsigned ones, the input operands just need to be swapped.
