E0072 update error format
Part of #35233Fixes#35506
r? @jonathandturner
The bonus for this issue currently seems to be impossible to do reliably, as the compiler seems to lack span information for item names alone, like `Foo` in `struct Foo { ... }`. It would be possible to hack something together by computing span offsets, but that seems like a solution that would be begging for trouble.
A proper solution to this would, of course, be to add span information to the right place (seems to be `rustc::hir::Item::name` but I may be wrong).
Update E0038 to the new error format
Part of #35233
Addresses #35500
"r? @jonathandturner
This doesn't compile yet, and I need help. In my naive solution, adding the span label makes our error message a mutable `errors::DiagnosticBuilder` pointer.
```bash
python src/bootstrap/bootstrap.py --step check-cfail E0038 --stage 1
```
```

Update e0017 to new format
Updated `span_err!` to use `struct_span_err!` and provide a `span_label` that describes the error in context.
Updated the test to look for the `span_label`s that are provided now.
refactor lvalue_ty to be method of lvalue
Currently `Mir` (and `MirContext`) implement a method `lvalue_ty` (and actually many more `foo_ty`). But this should be a method of `Lvalue`.
If you have an `lvalue` and you want to get its type, the natural thing to write is:
```
lvalue.ty()
```
Of course it needs context, but still:
```
lvalue.ty(mir, tcx)
```
Makes more sense than
```
mir.lvalue_ty(lvalue, tcx)
```
I actually think we should go a step farther and have traits so we could get the type of some value generically, but that's up for debate. The thing I'm running into a lot in the compiler is I have a value of type `Foo` and I know that there is some related type `Bar` which I can get through some combination of method calls, but it's often not as direct as I would imagine. Unless you already know the code, its not clear why you would look in `Mir` for a method to get the type of an `Lvalue`.
Print Rust target name, not LLVM target name, for `--print target-list`
Rust target name and LLVM target name are usually the same, but not always. For example, `arm-unknown-linux-musleabi` Rust target uses `arm-unknown-linux-gnueabi` LLVM target.
Fix#35481.
Point llvm @bitshifter branch until PR accepted
Use today's date for LLVM auto clean trigger
Update LLVM submodule to point at rust-lang fork.
Handle case when target is set
Add warning timeout for tests that run >1min
This makes it easier to identify hanging tests. As described in #2873,
when a test doesn't finish, we so far had no information on which test
that was. In this PR, we add a duration of 60 seconds for each test,
after which a warning will be printed mentioning that this specific test
has been running for a long time already.
