  PowerPC: Avoid MCSymbol::isUnset

"unset" is not a meaningful separae state and it will be merged into
"undefined".

https://reviews.llvm.org/D72570 ported a GAS hack that moves the label
when a prefixed instruction on the same source line needs automatic
alignment. However, we can used isDefined instead of isUnset.
