The scope of these refactorings is a little bit bigger than the title implies. See each commit for details.
I’m submitting this for nitpicking now (the first 4 commits), because I feel the basic idea/implementation is sound and should work. I will eventually expand this PR to cover the translator changes necessary for all this to work (+ tests), ~~and perhaps implement a dynamic dropping scheme while I’m at it as well.~~

Currently the `mipsel-unknown-linux-gnu` target doesn't actually set the
`target_arch` value to `mipsel` but it rather uses `mips`. Alternatively the
`powerpc64le` target does indeed set the `target_arch` as `powerpc64le`,
causing a bit of inconsistency between theset two.
As these are just the same instance of one instruction set, let's use
`target_endian` to switch between them and only set the `target_arch` as one
value. This should cut down on the number of `#[cfg]` annotations necessary and
all around be a little more ergonomic.
Some other shufflings as well:
* Three powerpc triples for Linux have been added recently
* An armv7 linux triple was added recently
* The 64-bit Solaris triple is now mentioned in tier 3
We are currently now also building nightlies for iOS, powerpc triples, and
armv7, but there hasn't been much vetting of the triples themselves so I've left
them in tier 3 for now.
Fixes#31334
This is just a quicker fix for this issue; since I'm working on the next draft of the book, I don't want to put a huuuge amount of work into improving it here.
Updated documentation to clarify the difference between `and_then` and `map`. This also explains why we need `and_then` in addition to `map`. Please look at the diff for more information.

Block comments don't have to be in the format `/*! ... !*/`
in order to be read as doc comments about the parent block.
The format `/*! ... */` is enough.
