Remove legacy InnoSetup GUI installer
On Windows the InnoSetup `.exe` installer was superseded by the MSI installer long ago. It's no longer needed.
The `.exe` installer hasn't been linked from the [other installation methods](https://forge.rust-lang.org/infra/other-installation-methods.html#standalone) page in many years. As far as I can tell the intent was always to remove this installer once the MSI proved itself. Though admittedly both installers feel very "legacy" at this point.
Removing this would mean we only maintain one Windows GUI installer and would speed up the distribution phase.
As a result of removing InnoSetup, this closes#24397
Replace old GDB and LLDB pretty-printers with new ones
which were originally written for IntelliJ Rust.
New LLDB pretty-printers support synthetic children.
New GDB/LLDB pretty-printers support all Rust types
supported by old pretty-printers, and also support:
Rc, Arc, Cell, Ref, RefCell, RefMut, HashMap, HashSet.
Test and fix gdb pretty printing more
Over time I had oversimplified the test case for #68098: it does not have an internal node to print so it did not test what it pretended to test. And then I also realized not spotting the same mistake reviewing #70111, and more likely to occur in the wild. Now, both test cases fail if you put back the flawed python code.

Teach `compiletest` to ignore platform triples
The UI tests are written assuming `--remap-path-prefix` is *not used* (`remap-debuginfo` in `config.toml`). The consequence is that the error messages may include paths and snippets into the standard library. When `remap-debuginfo` is enabled, these messages change in format and structure because `rustc` will not show paths and snippets into the standard library.
This normally isn't a problem for the "main" platforms (linux/macos/windows), because the CI infrastructure is set up so that the tests run without `remap-debuginfo`, but the `dist` artifacts are built separately with `remap-debuginfo` enabled. However, some of the lower-tier platforms perform both tests and distribution in a single step with `remap-debuginfo` enabled. This also affects developers and distributors who use `remap-debuginfo`.
To sidestep this problem, we add a way to ignore tests in specific platform triples, and update the overly broad `ignore-x86` rule in affected tests.
Address #46948, #54546, #53081.
debuginfo: Support for std::collections::Hash* in windows debuggers.
Okay, I finally needed to debug code involving a HashMap! Added support for HashSet s as well.

### Local Testing
Verified these are passing locally:
```cmd
:: cmd.exe
python x.py test --stage 1 --build x86_64-pc-windows-msvc src/test/debuginfo
python x.py test --stage 1 --build i686-pc-windows-msvc src/test/debuginfo
python x.py test --stage 1 src/tools/tidy
:: MinGW MSYS2
./x.py test --stage 1 --build x86_64-pc-windows-gnu src/test/debuginfo
```

I based this solution on my reading of:
https://rethinkdb.com/blog/make-debugging-easier-with-custom-pretty-printers#what-is-still-to-be-done
That post claims that there is no clean way to check for garbage pointers, and
so this PR adopts the same solution of tentatively attempting to convert a
dererence to a string, which throws a clean exception on garbage that we can
catch and recover from.
I only made the change to vec and not the other pretty printers because I wanted
to focus my effort on the simplest thing that would resolve issue #64343. In
particular, I *considered* generalizing this fix to work on the other datatypes
in the pretty-printing support library, but I don't want to invest effort in
that until after we resolve our overall debugging support strategy; see also
issues #60826 and #65564.
rustbuild: Turn down compression on msi installers
This is the same as #64615 except applied to our MSI installers. The
same fix is applied effectively bringing these installers in line with
the gz tarball installers, which are about 3x faster to produce locally
and likely much faster to produce on CI.

The Windows dist builders are the slowest builders right now, and the
distribution phase of them is enormously slow clocking in at around 20
minutes to build all the related installers. This commit starts to
optimize these by turning down the compression level in the `exe`
installers. These aren't super heavily used so there's no great need for
them to be so ultra-compressed, so let's dial back the compression
parameters to get closer to the rest of our xz archives. This brings the
installer in line with the gz tarball installer locally, and also brings
the compression settings on par with the rest of our xz installers.
This commit removes the `wasm_syscall` feature from the
wasm32-unknown-unknown build of the standard library. This feature was
originally intended to allow an opt-in way to interact with the
operating system in a posix-like way but it was never stabilized.
Nowadays with the advent of the `wasm32-wasi` target that should
entirely replace the intentions of the `wasm_syscall` feature.
Fix rust-lldb wrapper scripts.
Currently the `rust-lldb` wrapper provided by Rust project is broken. The error messages it produces on launch are as follows:

The errors stem from two regressions: one caused by an LLVM upgrade and one caused by unintended upgrade to SWIG 4.0 (SWIG is a wrapper generator that is used to generate Python bindings for LLVM and LLDB.)
(Edit: found the exact dates) The SWIG breakage happened because of a Homebrew version upgrade on `nightly-2019-05-01-x86_64-apple-darwin` and the LLVM breakage happened on `nightly-2019-01-27-x86_64-apple-darwin` (likely to have been caused by https://github.com/rust-lang/rust/pull/57675 ).
The fix is to update the LLVM parameter syntax and to "downgrade" to SWIG 3.0.x. SWIG 3.0.x is not going to be supported by Homebrew forever, but should be good for now, until LLDB upgrades to support SWIG 4.0.0. Here's some more info about Homebrew support: https://github.com/Homebrew/homebrew-core/pull/39929 & https://github.com/Homebrew/homebrew-core/pull/40882 I'm going to send a bug & fix to LLDB about SWIG 4.0.0 to get the situation fixed in the future.
It would be good to also backport this to beta, since it's such a small change, and will fix an obvious regression.
Updated to handle these changes:
- `core::ptr::*` lost their `__0` elements and are just plain pointers
- `core::ptr::*` probably shouldn't dereference in `DisplayString` s
- `VecDeque` and `Vec` use `core::ptr::*` s
- `VecDeque` and `LinkedList` moved modules again.
Retested - still working fine, left alone:
- `String`, `&str`, `Option`
