fail_bounds_check in unstable.rs should return ! #10023
Description
This tells LLVM that the function returns, and will hopefully help codegen to place the failing bounds check function calls at the end of the codegen'd function instead of inline with the rest of the code.
It would also be great to have a before/after analysis of some bounds checks to see if this improves codegen at all.
