  Changed paths:
    M clang/lib/Sema/SemaDecl.cpp
    A clang/test/SemaObjC/block-capture-unused-variable.m

  Log Message:
  -----------
  [clang] 'unused-but-set-variable' warning should not apply to __block objective-c pointers

The __block Objective-C pointers can be set but not used due to a commonly used lifetime extension pattern in Objective-C.
