[PATCH] D55544: Warning: objc-encodings-larger-than=

[Dave MacLachlan via Phabricator via cfe-commits]

Issue a warning when the Objective C runtime encoding generated for an iVar, method, or block exceeds a user configurable value.

Off by default.

Note that handling iVars and methods will also get us properties.

Objective C runtime information can get very large (several K) and most of it is unused. Having the warning allows us to diagnose where the problem exists in our code.
