[PATCH] D70973: [OPENMP50]Treat context selectors as expressions, not just strings.

[Johannes Doerfert via Phabricator via cfe-commits]

jdoerfert added a comment.

I haven't forgotten about this! With the other two changes to the declare variant going to happen now,as well, I figured we should look at this again from a high-level.

My plan now is:

1. Move all of the declare variant context stuff out of clang into the libFrontendOpenMP. This has various benefits, including reuse capabilities and the problem of where to put it (which was discussed briefly in my other declare variant patches), is gone.
2. Set it up to accept *constant* strings and non-string alike from the beginning. I'll also make it completely OMPKinds.def based with all the trait sets and selectors at least parsed properly. Rules what can be nested together, what can have a score, etc. are all reusable and mostly generated.
3. Introduce the declare variant begin/end stuff to get math support before the 10 fork.
4. Make all declare variant decisions in SemaOverload.
