[backported/clang-7][libclang] Support querying whether a declaration is invalid
------------------------------------------------------------------------
* Enables fix for https://bugreports.qt.io/browse/QTCREATORBUG-18686
------------------------------------------------------------------------
This is useful for e.g. highlighting purposes in an IDE.
Note: First version of this patch was reverted due to failing tests in
opencl-types.cl with -target ppc64le-unknown-linux. These tests are
adapted now.
Patch by Nikolai Kosjar.
