Improve `ptr_rotate` performance, tests, and benches The corresponding issue is rust-lang#61784. I am not actually sure if miri can handle the test, but I can change the commit if necessary.

@alexcrichton

Update LLVM submodule This pulls in a newer version of the LLVM 9 release branch. Fixes rust-lang#62932. r? @alexcrichton

Tweak mismatched types error - Change expected/found for type mismatches in `break` - Be more accurate when talking about diverging match arms - Tweak wording of function without a return value - Suggest calling bare functions when their return value can be coerced to the expected type - Give more parsing errors when encountering `foo(_, _, _)` Fix rust-lang#51767, fix rust-lang#62677, fix rust-lang#63136, cc rust-lang#37384, cc rust-lang#35241.
