John McCall e68b8f4dcc At -O0, prefer objc_storeStrong with a null new value to the 
combination of a load+objc_release;  this is generally better
for tools that try to track why values are retained and
released.  Also use objc_storeStrong when copying a block
(again, only at -O0), which requires us to do a preliminary
store of null in order to compensate for objc_storeStrong's
assign semantics.

John McCall 9701731a3e When initializing a catch variable in ARC, be sure to emit retains 
or whatever else is required for the initialization instead of
assuming it can be done with a simple store.

Fixes PR11732.
