John Brawn	9486becf09	[ARM] Mark LEApcrel instructions as isAsCheapAsAMove ... Doing this means that if an LEApcrel is used in two places we will rematerialize instead of generating two MOVs. This is particularly useful for printfs using the same format string, where we want to generate an address into a register that's going to get corrupted by the call.
