Fixes rust-lang#44971

Due to rust-lang/cargo#4570, a `*.dll.lib` file is uplifted when building
dynamic libraries on Windows. The current bootstrap code does not
understand files with multiple extensions, and will instead assume
`xxxx.dll` is the file name. This caused a `no output generated` error
because it tries to search for `xxxx.dll-hash.lib` inside the `deps/`
folder, while it should check for `xxxx-hash.dll.lib` instead.

This PR is blocking rust-lang#45285 (Bump to 1.23 and update bootstrap).

Similar to rust-lang#36994, rust programs segfault on SPARC64 Solaris machines.

This was accidentally added in rust-lang#45352, forgot to back it out!

Correct misspelling in error text: re-assignment => reassignment

[reassignment is the correct spelling](https://www.thefreedictionary.com/reassignment) rather than re-assignment; this error message looks silly in the book next to text trying to be grammatically correct :-/

Will this cause any stability/backcompat type issues?

Implement Hash for raw pointers to unsized types

This is useful for some niche cases, like a hash table of slices or trait objects where the key is the raw pointer.  Example use case: https://docs.rs/by_address
