Emit proper lifetime start intrinsics for personality slots We currently only emit a single call to the lifetime start intrinsic for the personality slot alloca. This happens because we create that call at the time that we create the alloca, instead of creating it each time we start using it. Because LLVM usually removes the alloca before the lifetime intrinsics are even considered, this didn't cause any problems yet, but we should fix this anyway.

Run rustfmt on `tests/codegen/`. Except for `simd-intrinsic/`, which has a lot of files containing multiple types like `u8x64` which really are better when hand-formatted. There is a surprising amount of two-space indenting in this directory. Non-trivial changes: - `rustfmt::skip` needed in `debug-column.rs` to preserve meaning of the test. - `rustfmt::skip` used in a few places where hand-formatting read more nicely: `enum/enum-match.rs` - Line number adjustments needed for the expected output of `debug-column.rs` and `coroutine-debug.rs`.
