This new verifier rule lets us unambigously pick a calling convention when creating a new declaration for `@llvm.experimental.deoptimize.<ty>`. It is also congruent with our lowering strategy -- since all calls to `@llvm.experimental.deoptimize` are lowered to calls to `__llvm_deoptimize`, it is reasonable to enforce a unique calling convention. Some of the tests that were breaking this verifier rule have had to be split up into different .ll files. The inliner was violating this rule as well, and has been fixed to avoid producing invalid IR. llvm-svn: 269261
