[flang-commits] [flang] [llvm] [flang][OpenMP] Semantic checks for context selectors (PR #123243)

[Tom Eccles via flang-commits]

https://github.com/tblah approved this pull request.

The code changes look good to me and as far as I can tell the semantic changes look correct to the standard.

I'm tentatively approving but it would be great if somebody else can look over this as this is my first look at METADIRECTIVE. Feel free to merge if nobody else takes a look in the near future.
