Subject: Allow the Mac and iOS Breakpad clients to build without exceptions
 when the C++ standard library is not provided by libstdc++. libc++, for
 example, does not provide its own try and catch replacement macros when
 exceptions are disabled.

BUG=509
Review URL: https://breakpad.appspot.com/503002
