Update Boost in 3rdParty to version 1.56.0.

This updates Boost in our 3rdParty directory to version 1.56.0. Updated our update.sh script to stop on error. Changed error reporting in SwiftTools/CrashReporter.cpp to SWIFT_LOG due to missing include of <iostream> with newer Boost. Change-Id: I4b35c77de951333979a524097f35f5f83d325edc
