New Revision: 293199

URL: http://llvm.org/viewvc/llvm-project?rev=293199&view=rev
Log:
Turn on -Wblock-capture-autoreleasing by default.

Turning on the warning by default helps the users as it's a common
mistake to capture out-parameters in a block without ensuring the object
assigned doesn't get released.
