[CodeGen][ObjC] Annotate retain-agnostic ObjC globals with attribute
'objc_arc_inert'
The attribute enables the ARC optimizer to delete ObjC ARC runtime calls
on the annotated globals (see https://reviews.llvm.org/D62433). We
currently only annotate global variables for string literals and global
blocks with the attribute.
