Fix PR8828 by removing the explicit def in MovePCToLR as well as the pointless 

piclabel operand. The operand in the tablegen definition doesn't actually turn
into an MI operand, so it just confuses anything checking the TargetInstrDesc
for the number of operands. It suffices to just have an implicit def of LR.
