[PATCH] D24371: Add diagnostics to require_constant_initialization

[Richard Smith via cfe-commits]

rsmith added a comment.

There's no way for `-verify` to test for a diagnostic with an invalid location at the moment. Maybe add a FIXME and disable that portion of the test for C++11?

----------------
Can you capture the diagnostics from `checkInitIsICE` instead of recomputing them here? (It looks straightforward to add an overload that takes a vector of notes.) In the non-C++11 case, you can produce a note pointing to `CacheCulprit` instead.
