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

Note that on compilers that support variadic macros (most of moder compliers

allows to specify the capture list as a Boost.Preprocessor sequence of tokens
(for supporting compilers without variadic macros and for backward compatibility with older versions of this library).
The name <c>variable</c> of each captured variable must be a valid name in the
enclosing scope and it must appear exactly once in the capture list.
If a capture starts with the ampersand sign <c>&</c>, the corresponding
variable will be available by reference within the scope exit body; otherwise,
a copy of the variable will be made at the point of the scope exit declaration
and that copy will be available inside the scope exit body (in this case, the
variable's type must be <c>CopyConstructible</c>).
From within a member function, the object <c>this</c> can be captured using the
special name <c>this_</c> in both the capture list and the scope exit body
(using <c>this</c> instead of <c>this_</c> in the scope exit body leads to
undefined behaviour).
It is possible to capture no variable by specifying the capture list as

which is in general different from the legacy capture syntax of this library.
For example, C++11 lambdas require to capture data members by capturing the
object <c>this</c> while this library always allowed to capture data members
directly.
Therefore, when this configuration macro is defined,
@RefMacro{BOOST_SCOPE_EXIT} and @RefMacro{BOOST_SCOPE_EXIT_TPL} are no longer
backward compatible (and this is why this macro is not defined by default).
A semicolon <c>;</c> can be used instead of @RefMacro{BOOST_SCOPE_EXIT_END}
when this configuration macro is defined (but it is recommended to always use
@RefMacro{BOOST_SCOPE_EXIT_END} so to maximize portability).
@Note This configuration macro does not control the definition of
@RefMacro{BOOST_SCOPE_EXIT_ALL} which is always and automatically defined on
compilers that support C++11 lambda functions.
@See @RefMacro{BOOST_SCOPE_EXIT}, @RefMacro{BOOST_SCOPE_EXIT_TPL},
@RefMacro{BOOST_SCOPE_EXIT_END}.
