This commit adds a traversal of the AST after Sema of a function that diagnoses unguarded references to declarations that are partially available (based on availability attributes). This traversal is only done when we would otherwise emit -Wpartial-availability. This commit is part of a feature I proposed here: http://lists.llvm.org/pipermail/cfe-dev/2016-July/049851.html Differential revision: https://reviews.llvm.org/D23003 llvm-svn: 278826
