[PATCH] D142584: [CodeGen] Add a boolean flag to `Address::getPointer` and `Lvalue::getPointer` that indicates whether the pointer is known not to be null

[Eli Friedman via Phabricator via cfe-commits]

I'm having a little trouble following what the meaning of an "Address" is with 
this patch.  The `Pointer` member refers to an encoded value, and calling 
getPointer() emits IR to decode it?  Could use a few comments to explain the 
API.
