b1858447d3 fix confusion about parts required for float formatting
The documentation for flt2dec doesn't match up with the actual
implementation, so fix the documentation to align with reality.
Presumably due to the mismatch, the formatting code for floats in
std::fmt can use correspondingly shorter arrays in some places, so fix
those places up as well.

Fixes #41304.

[Doc] improve `thread::Thread` and `thread::Builder` documentations

Part of #29378

- Adds information about the stack_size when using `Builder`. This might be considered too low level, but I assume that if someone wants to create their own builder instead of using `thread::spawn` they may be interested in that info.
- Updates the `thread::Thread` structure doc, mostly by explaining how to get one, the previous example was removed because it was not related to `thread::Thread`, but rather to `thread::Builder::name`.
  Not much is present there, mostly because this API is not often used (the only method that seems useful is `unpark`, which is documented in #41809).

incr.comp.: Hash more pieces of crate metadata to detect changes there.

This PR adds incr. comp. hashes for non-`Entry` pieces of data in crate metadata.

The first part of it I like: `EntryBuilder` is refactored into the more generally applicable `IsolatedEncoder` which provides means of encoding something into metadata while also feeding the encoded data into an incr. comp. hash. We already did this for `Entry`, now we are doing it for various other pieces of data too, like the set of exported symbols and so on. The hashes generated there are persisted together with the per-`Entry` hashes and are also used for dep-graph dirtying the same way.

The second part of the PR I'm not entirely happy with: In order to make sure that we don't forget registering a read to the new `DepNodes` introduced here, I added the `Tracked<T>` struct. This struct wraps a value and requires a `DepNode` when accessing the wrapped value. This makes it harder to overlook adding read edges in the right places and works just fine.
However, crate metadata is already used in places where there is no `tcx` yet or even in places where no `cnum` has been assigned -- this makes it harder to apply this feature consistently or implement it ergonomically. The result is not too bad but there's a bit more code churn and a bit more opportunity to get something wrong than I would have liked. On the other hand, wrapping things in `Tracked<T>` already has revealed some bugs, so there's definitely some value in it.

This is still a work in progress:
- [x] I need to write some test cases.
- [x] Accessing the CodeMap should really be dependency tracked too, especially with the new path-remapping feature.

dump-mir was causing cycles by invoking item-path-str at bad times

Workaround for now, but probably a better fix is to opt **in** to using the types for impls (if we do that at all; maybe filename/line is better).

Remove need for &format!(...) or &&"" dances in `span_label` calls

These were always a thorn in my eye. Note that this will monomorphize to two impls, one for `String` and one for `&str`. But I think that cost is worth the ergonomics at the call sites that can be seen throughout this PR.

Add support for Hexagon v60 HVX intrinsics

HVX is a SIMD coprocessor available on newer hexagon cores. It can be configured for 512 or 1024 bit registers, and some instructions use pairs of registers. It only does integer operations, but it probably has every integer operation you'd want for 8/16/32 bit elements.

There are a lot of intrinsics. The generator outputs 582 of them. I probably got some wrong. I did some scripting to make sure that every llvm intrinsic name exists, but intrinsic names provided for programs have only been compared by eye to Qualcomm's own names. 64/128 is also appended to the names to select between 512/1024 bit. The C intrinsics don't do this, but they only expose one set, selected at compile time.

The json specifying the intrinsics required a bit of duplication since I didn't see an easy way to specify combinations of signed/unsigned types (eg. u(8-16) and s(16-32)). I also didn't see an easy way to specify variants of instructions like saturating or rounding.

Basic multiplication and load/store tested on the hexagon simulator.
