Port streaming commands in bootstrap to `BootstrapCommand` and remove `as_command_mut`
This PR adds streaming capabilities to BootstrapCommand and migrate existing command streaming scenario's used in bootstrap.

remove armv5te-unknown-linux-gnueabi target maintainer
Sadly my former employer doesn't want to maintain this any more and I have no personal interest in maintaining it.
Stop using `Key` trait unnecessarily
Few places where the `Key` trait was being used but not really for a useful reason. This fixes those usages.
Namely, `<Ty as Key>::default_span()` is `DUMMY_SP` anyways.
Canonicalize input ty/ct infer/placeholder in the root universe
We shouldn't care what universe the inputs are, since we only ever do the leak check on the universes instantiated after entering the canonical binder.
[COMPILETEST-UNTANGLE 4/N] Improve compiletest config documentation
This is part of a patch series to untangle `compiletest` to hopefully nudge it towards being more maintainable.
This PR should contain **no functional changes**.
This is pulled out to its own PR to make follow-up changes easier to review.
There are *intentionally* a *lot* of FIXME comments, intended to be gradually addressed in follow-ups.

move `va_copy`, `va_arg` and `va_end` to `core::intrinsics`
some questions:
- should these functions be `pub`?
- is a separate module justified?

codegen_ssa: replace a Result by an Either
`Err` here clearly does not indicate an "error" of any sort, so the use of `Result` is confusing. Let's use a sum type that does not come with the baggage of `Result`.
Pretend in bootstrap snapshot tests that we always build in-tree LLVM
Otherwise, depending on whether CI LLVM is inhibited or if an externally-provided LLVM is used, bootstrap host LLVM build step could be missing in step snapshots.
Note that I'm not sure if this is the *right* solution (this might be *a* solution). I imagine we do want to control for the set of configuration that these snapshot tests are run, as much as possible.

Remove `Symbol` from `Named` variant of `BoundRegionKind`/`LateParamRegionKind`
The `Symbol` is redundant, since we already store a `DefId` in the region variant. Instead, load the name via `item_name` when needed (which is almost always on the diagnostic path).
This introduces a `BoundRegionKind::NamedAnon` which is used for giving anonymous bound regions names, but which should only be used during pretty printing and error reporting.
Fix CLI completion check in `tidy`
The list of CLI completion files that were generated and that were checked by `x test tidy` was not synced. Recently, some PR only updated some of the files, which caused the rest of the files (not checked by `x test tidy`) to be dirty on `master`. This PR fixes the logic in bootstrap to always synchronize the list of completion paths.

test passing a `VaList` from rust to C
Have C define various functions that take a `...` or `va_list` as an argument, and call them from rust. As far as I can see, this just wasn't actually tested before.
In particular this tests a difference between rust `VaList` and C `va_list` where C uses array-to-pointer decay, but rust cannot.
I've locally tested this for
- `x86_64-unknown-linux-gnu`
- `aarch64-unknown-linux-gnu`
- `s390x-unknown-linux-gnu`
- `powerpc64-unknown-linux-gnu`
- `powerpc64le-unknown-linux-gnu`
The latter 2 use an opaque pointer, the first 3 use a single-element array.

Allow `enum` and `union` literals to also create SSA values
Today, `Some(x)` always goes through an `alloca`, even in trivial cases where the niching means the constructor doesn't even change the value.
For example, <https://rust.godbolt.org/z/6KG6PqoYz>
```rust
pub fn demo(r: &i32) -> Option<&i32> {
Some(r)
}
```
currently emits the IR
```llvm
define align 4 ptr `@demo(ptr` align 4 %r) unnamed_addr {
start:
%_0 = alloca [8 x i8], align 8
store ptr %r, ptr %_0, align 8
%0 = load ptr, ptr %_0, align 8
ret ptr %0
}
```
but with this PR it becomes just
```llvm
define align 4 ptr `@demo(ptr` align 4 %r) unnamed_addr {
start:
ret ptr %r
}
```
(Of course the optimizer can clean that up, but it'd be nice if it didn't have to -- especially in debug where it doesn't run. This is like rust-lang/rust#123886, but that only handled non-simd `struct`s -- this PR generalizes it to all non-simd ADTs.)
Doing this means handing variants other than `FIRST_VARIANT`, handling the active field for unions, refactoring the discriminant code so the Place and Operand parts can share the calculation, etc.
