[PATCH] D79279: Add overloaded versions of builtin mem* functions

[JF Bastien via Phabricator via cfe-commits]

jfb updated this revision to Diff 285414.
jfb added a comment.

Update overloading as discussed: on the original builtins, and separate the _sized variant, making its 4th parameter non-optional. If this looks good, I'll need to update codege for a few builtins (to handle volatile), as well as add tests for their codegen and address space (which should already work, but isn't tested).
