[PATCH] D62009: [clang] perform semantic checking in constant context

[Richard Smith - zygoloid via Phabricator via cfe-commits]

rsmith added a comment.

The approach we've been taking for this up until now is to use a `ConstantExpr` node to mark the entry point of a constant context; it looks like that would continue to work here, but we're missing those nodes in some cases? (This is preferable to using a flag because it also -- eventually -- gives us a place to store the evaluated value, which we're going to need for various upcoming features, particularly `consteval`.)
