Re-add help_on_error for download-ci-llvm
Closes#97503
- Re-added `help_on_error` for `download_component()` and the downstream functions
- Removed dead code in `bootstrap.py`
Thanks `@jyn514` for the helpful tips!

Resubmission of #89268, fixes#71363
The behavior difference of `simulate-remapped-rust-src-base` is not something we should take into account here, so limiting targets to run the test makes sense, I think.

Remove "sys isn't exported yet" phrase
The oldest occurence is from 9e224c2bf1,
which is from the pre-1.0 days. In the years since then, std::sys still
hasn't been exported, and the last attempt was met with strong criticism:
https://github.com/rust-lang/rust/pull/97151
Thus, removing the "yet" part makes a lot of sense.
Use Box::new() instead of box syntax in library tests
The tests inside `library/*` have no reason to use `box` syntax as they have 0 performance relevance. Therefore, we can safely remove them (instead of having to use alternatives like the one in #97293).

Replace `#[default_method_body_is_const]` with `#[const_trait]`
pulled out of #96077
related issues: #67792 and #92158

This is groundwork to only allowing `impl const Trait` for traits that are marked with `#[const_trait]`. This is necessary to prevent adding a new default method from becoming a breaking change (as it could be a non-const fn).
Finish bumping stage0
It looks like the last time had left some remaining cfg's -- which made me think
that the stage0 bump was actually successful. This brings us to a released 1.62
beta though.
This now brings us to cfg-clean, with the exception of check-cfg-features in bootstrap;
I'd prefer to leave that for a separate PR at this time since it's likely to be more tricky.

Prepare Rust for opaque pointers
Fix one codegen bug with opaque pointers, and update our IR tests to accept both typed pointer and opaque pointer IR. This is a bit annoying, but unavoidable if we want decent test coverage on both LLVM 14 and LLVM 15.
This prepares Rust for when LLVM will enable opaque pointers by default.
Move download-rustc from python to rustbuild
- Remove download-rustc handling from bootstrap.py
- Allow a custom `pattern` in `builder.unpack()`
- Only download rustc once another part of bootstrap depends on it.
This is somewhat necessary since the download functions rely on having a full
`Builder`, which isn't available until after config parsing finishes.
Helps with https://github.com/rust-lang/rust/issues/94829.

ptr::invalid is not equivalent to a int2ptr cast
I just realized I forgot to update these docs when adding `from_exposed_addr`.
Right now the docs say `invalid` and `from_exposed_addr` are both equivalent to a cast, and that is clearly not what we want.

Make some tests check-pass
This touches the tests related to lint, parser, and importing, all of them should be fine with `check-pass`.
r? ``@compiler-errors``
Remove FIXME on `ExtCtxt::fn_decl()`
`ExtCtxt::fn_decl()` is used like `self.fn_decl(..)` or `self.cx.fn_decl(..)`, coverting it to an assoc fn, for example, makes it inconvenience (e.g. `self.cx.fn_decl(..)` would be longer to represent). Given that, it doesn't seem a "FIXME" thing and unused `self` is okay, I think.
Add support for embedding pretty printers via `#[debugger_visualizer]` attribute
Initial support for [RFC 3191](https://github.com/rust-lang/rfcs/pull/3191) in PR https://github.com/rust-lang/rust/pull/91779 was scoped to supporting embedding NatVis files using a new attribute. This PR implements the pretty printer support as stated in the RFC mentioned above.
This change includes embedding pretty printers in the `.debug_gdb_scripts` just as the pretty printers for rustc are embedded today. Also added additional tests for embedded pretty printers. Additionally cleaned up error checking so all error checking is done up front regardless of the current target.
