This patch adds a new extension to the `omp begin / end declare variant` support that causes it to apply to function declarations as well. This is explicitly not done in the standard, but can be useful in some situations so we should provide it as an extension. This will allow us to uniquely bind and overload existing definitions with a simple declaration using variants. Reviewed By: jdoerfert Differential Revision: https://reviews.llvm.org/D124624
