All llvm.deoptimize declarations must use the same calling convention 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

MCStreamer: Use "cfi" for CFI related temp labels. Choosing a "cfi" name makes the intend a bit clearer in an assembly dump and more importantly the assembly dumps are slightly more stable as the numbers don't move around anymore when unrelated code calls createTempSymbol() more or less often. As they are temp labels the name doesn't influence the generated object code. Differential Revision: https://reviews.llvm.org/D27244 llvm-svn: 288290
