Nemanja Ivanovic e009fad342 [PowerPC] Remove UB from PPCInstrInfo when handling rotates fed by constants ...

As pointed out in https://bugs.llvm.org/show_bug.cgi?id=45232 this code can
end up shifting a 64-bit unsigned value left by 64 bits. Althought this works
as expected on some platforms it is definitely UB. This patch removes the UB
and adds the associated test case.
