This will allow better strategies for use of memory and File handles. However, fully taking advantage of that is left to future work.

It's possible that a file in the directory is pending deletion. In that case we might succeed after a few attempts.

rust-lang#91318 introduced a trait for infallible folders distinct from the fallible version.  For some reason (completely unfathomable to me now that I look at it with fresh eyes), the infallible trait was a supertrait of the fallible one: that is, all fallible folders were required to also be infallible.  Moreover the `Error` associated type was defined on the infallible trait!  It's so absurd that it has me questioning whether I was entirely sane.

This trait reverses the hierarchy, so that the fallible trait is a supertrait of the infallible one: all infallible folders are required to also be fallible (which is a trivial blanket implementation).  This of course makes much more sense!  It also enables the `Error` associated type to sit on the fallible trait, where it sensibly belongs.

There is one downside however: folders expose a `tcx` accessor method.  Since the blanket fallible implementation for infallible folders only has access to a generic `F: TypeFolder`, we need that trait to expose such an accessor to which we can delegate.  Alternatively it's possible to extract that accessor into a separate `HasTcx` trait (or similar) that would then be a supertrait of both the fallible and infallible folder traits: this would ensure that there's only one unambiguous `tcx` method, at the cost of a little additional boilerplate.  If desired, I can submit that as a separate PR.

Windows: Iterative `remove_dir_all`

This will allow better strategies for use of memory and File handles. However, fully taking advantage of that is left to future work.

Note to reviewer: It's probably best to view the `remove_dir_all_recursive` as a new function. The diff is not very helpful (imho).

Mitigate MMIO stale data vulnerability

Intel publicly disclosed the MMIO stale data vulnerability on June 14. To mitigate this vulnerability, compiler changes are required for the `x86_64-fortanix-unknown-sgx` target.

Suggest defining variable as mutable on `&mut _` type mismatch in pats

Suggest writing `mut a` where `&mut a` was written but a non-ref type provided.

Since we still don't have "apply either one of the suggestions but not both" kind of thing, the interaction with the suggestion of removing `&[mut]` or moving it to the type is weird, and idk how to make it better..
