[LLVMdev] LLD: Returning true on success

[Rui Ueyama]

It looks like although it's not mentioned in the coding standard, nobody is
opposing to invert it for this case, so I'll do it. I agree with Michael.
Returning true on success seems natural to me. However, I believe the most
important thing is to maintain consistency of boolean return value at
least within LLD whether it should be true or false.
