[PATCH] D69407: build: remove `LLVM_CXX_STD` extension point

[Saleem Abdulrasool via Phabricator via llvm-commits]

compnerd added a comment.

My reasoning behind that was that it seemed that some people were concerned about cached variables not being easy to remove in subsequent updates.  This will now default to 14, but allow the user to specify a different value.
