[CodeGen] Fix assertion on referencing constexpr Obj-C object with ARC.
Failed assertion is
> Assertion failed: ((ND->isUsed(false) || !isa<VarDecl>(ND) || !E->getLocation().isValid()) && "Should not use decl without marking it used!"), function EmitDeclRefLValue, file llvm-project/clang/lib/CodeGen/CGExpr.cpp, line 2437.
`EmitDeclRefLValue` mentions
> // A DeclRefExpr for a reference initialized by a constant expression can
> // appear without being odr-used. Directly emit the constant initializer.
The fix is to use the similar approach for non-references as for references. It
is achieved by trying to emit a constant before we attempt to load non-odr-used
variable as LValue.
