[PATCH] D52750: [Diagnostics] Check for integer overflow in array size expressions

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

rsmith added a comment.

We're going to try evaluating the array size anyway (in `isArraySizeVLA`). It would be much better to produce the overflow warnings as part of that evaluation rather than adding an extra evaluation step to produce them.
