Define Q_CC_CLANG to be the version of upstream Clang that's in use

Browse Source 
We map the Apple Clang versions to upstream, so that we have one
define to compare against.

Fixes build break on iOS due to qbasicatomic.h not defining
QT_BASIC_ATOMIC_HAS_CONSTRUCTORS on Apple Clang versions, which
is needed after 1e9db9f5e18123f2e686c10b
