This patch fixes the #67002 ([OpenMP][Clang] Scan Directive not supported for
Generic types). It disables the Sema checks/analysis that are run on the helper
arrays which go into the implementation of the `omp scan` directive until the
template instantiation happens.
Grateful to @alexey-bataev for suggesting these changes.
