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

-// Revision History
-// 04 Mar 2001 - More attempted fixes for Intel C++ (David Abrahams)
-// 03 Mar 2001 - Put all implementation into namespace
-// boost::detail::iterator_traits_. Some progress made on fixes
-// for Intel compiler. (David Abrahams)
-// 02 Mar 2001 - Changed BOOST_MSVC to BOOST_MSVC_STD_ITERATOR in a few
-// places. (Jeremy Siek)
-// 19 Feb 2001 - Improved workarounds for stock MSVC6; use yes_type and
-// no_type from type_traits.hpp; stopped trying to remove_cv
-// before detecting is_pointer, in honor of the new type_traits
-// semantics. (David Abrahams)
-// 13 Feb 2001 - Make it work with nearly all standard-conforming iterators
-// under raw VC6. The one category remaining which will fail is
-// that of iterators derived from std::iterator but not
-// boost::iterator and which redefine difference_type.
-// 11 Feb 2001 - Clean away code which can never be used (David Abrahams)
-// 09 Feb 2001 - Always have a definition for each traits member, even if it
-// can't be properly deduced. These will be incomplete types in
-// some cases (undefined<void>), but it helps suppress MSVC errors
-// elsewhere (David Abrahams)
-// 07 Feb 2001 - Support for more of the traits members where possible, making
-// this useful as a replacement for std::iterator_traits<T> when
-// used as a default template parameter.
-// 06 Feb 2001 - Removed useless #includes of standard library headers
-// (David Abrahams)
