[dsymutil] Perform analyzeContextInfo and CloneDIEs in parallel
This patch makes dsymutil perform analyzeContextInfo and CloneDIEs in parallel. For the same object file, there is a dependency between the two. However, we can do analyzeContextInfo for the next object file while cloning DIEs for the current. This is exactly the approach taken in this patch. For WebCore, this leads to a performance improvement of 29% and for clang we see similar results with at 32% improvement. A big thanks to Pete Cooper who came up with the original idea and the PoC.
