\| \| \| \| \| \| \| \|	objc_retainBlock call is potentially responsible for copying the block to the heap to extend its lifetime. rdar://10209613. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140814 91177308-0d34-0410-b5e6-96231b3b80d8

*	Track a retain+release nesting level independently of the	Dan Gohman	2011-08-19	1	-0/+68
\| \| \| \| \| \| \| \| \|	known-incremented level, because the two concepts can be used to prove the saftey of a retain+release removal in different ways. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138016 91177308-0d34-0410-b5e6-96231b3b80d8

Note that this change affects the existing non-atomic load and store instructions; the parser now accepts both forms, and the change is noted in the release notes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137527 91177308-0d34-0410-b5e6-96231b3b80d8
