[analyzer] Avoid ProgramStateRef copy constructors. Suggested by David Blaikie. ExplodedNode, CallEvent, and CheckerContext all hang onto their ProgramState, so the accessors can return a reference to the internal state rather than preemptively copying it. This helps avoid temporary ProgramStateRefs, though local variables will still (correctly) do an extra retain and release. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169563 91177308-0d34-0410-b5e6-96231b3b80d8
