Akira Hatanaka 65046abf79 [ObjCARC] Do not move a release that has the clang.imprecise_release tag ...

above PHI instructions.

ARC optimizer has an optimization that moves a call to an ObjC runtime
function above a phi instruction when the phi has a null operand and is
an argument passed to the function call. This optimization should not
kick in when the runtime function is an objc_release that releases an
object with precise lifetime semantics.
