define QT_NO_EXCEPTIONS reliably when using Clang
Clang's definition of the __EXCEPTIONS macro is inconsistent across
platforms. When compiling for Darwin, Clang 3.6 and newer will set the
token when exceptions are enabled in either C++ or ObjC. This change
adds the reliable check described in the Clang 3.6 release notes to
ensure that QT_NO_EXCEPTIONS is defined when required.
The check requires the use of the Clang-specific __has_feature()
syntax for which a new proxy macro QT_HAS_FEATURE(x) is added in
