The clang half of r150794: after the construction of a global or static const variable ends, if the variable has a trivial destructor and no mutable subobjects then emit an llvm.invariant.start call for it. globalopt knows to make the variable const when evaluating this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150798 91177308-0d34-0410-b5e6-96231b3b80d8
