Fix diff option conflict in UI test

Trivial fix for test case `tests/run-make/rustdoc-verify-output-files`,
it's failing on MacOS, the `-u` option specifies the unified context format, while the `-q` option specifies only brief output. These two options are incompatible, since the unified context format produces a more detailed output than the brief output format.

Check for body owner fallibly in error reporting

Sometimes the "body id" we use for an obligation cause is not actually a body owner, like when we're doing WF checking on items.

Added diagnostic for pin! macro in addition to Box::pin if Unpin isn't implemented

I made a PR earlier, but accidentally renamed a branch and that deleted the PR... sorry for the duplicate

Currently, if an operation on `Pin<T>` is performed that requires `T` to implement `Unpin`, the diagnostic suggestion is to use `Box::pin` ("note: consider using `Box::pin`").

This PR suggests pin! as well, as that's another valid way of pinning a value, and avoids a heap allocation. Appropriate diagnostic suggestions were included to highlight the difference in semantics (local pinning for pin! vs non-local for Box::pin).
