Fix debugging builds with Clang 3.2 and up.

Browse source 
In those Clang versions, -fcatch-undefined-behavior was replaced by
-fsanitize=<what>.  For Clang 3.2, we enable the address sanitizer
and for 3.3 also the miscellaneous undefined behavior one.
Currently, there's no version auto-detection from the Makefiles, it's
set to 3.3 and the others are commented out.
