3029e0918d Auto merge of #31726 - jseyfried:improve_import_resolution, r=nikomatsakis
This PR improves the import resolution algorithm.

First, it records that an import succeeded or failed for one namespace (by calling `decrement_outstanding_references_for` and `try_define_child` if successful) even if it is still indeterminate in the other namespace, fixing #31444.

Second, it starts importing bindings from globs as soon as the glob path is determined.
It maintains links from imported modules to their importers so that when a resolution becomes successful in an imported module, a corresponding binding will be added to the importer module.
It also maintains links from importer modules to imported modules so that we can determine if an undefined name is indeterminate or failing by recursively checking this in the imported modules.
This allows, for example:
```rust
mod foo {
    pub mod baz {}
    pub use bar::baz::*;
}

mod bar {
    pub use foo::*;
}
```
It also allows cycles of pub glob imports, although by to the current shadowing rules, the only way for such a cycle to compile is if each participating module defines no names. Incidentally, this PR lays the groundwork for more permissive feature-gated shadowing rules.

Finally, this PR encapsulates almost all implementation details of import resolution in `resolve_imports` (some of which used to be in `lib.rs`) and refactors reexport recording, shadowed trait collecting, some duplicate checking, and the `private_in_public` lint out of the core import resolution algorithm and into a post-processing pass in `resolve_imports`.

4594f0f67a Fix panic on string slicing error to truncate the string
The string may be arbitrarily long, but we want to limit the panic
message to a reasonable length. Truncate the string if it is too long
(simply to char boundary).

Also add details to the start <= end message. I think it's ok to flesh
out the code here, since it's in a cold function.

8872163b32 Define x86 fused multiply-add intrinsics
This defines the following intrinsics for 128 and 256 bit vectors of f32
and f64:

 * `fmadd`
 * `fmaddsub`
 * `fmsub`
 * `fmsubadd`
 * `fnmadd`
 * `fnmsub`

The `_sd` and `_ss` variants are not included yet.

Intel intrinsic reference: https://software.intel.com/en-us/node/523929

The intrinsics there are listed under AVX2, but in the Intel Intrinsic
Guide they are part of the "FMA" technology, and LLVM puts them under
FMA, not AVX2.

7fdb9fd941 More reliable and consistent method of cancelling -Werror*
Adding -Wno-error is more reliable and simple than trying to modify existing
flags. We've been using this in Debian already for the past few releases.
Making this change also encourages future maintainers towards "best practises".
Also take the opportunity to use the same method at all places in the file.

a03222c2b1 Do not trigger unused_assignments for overloaded AssignOps
If `v` were a type with some kind of indirection, so that `v += 1` would
have an effect even if `v` were not used anymore, the unused_assignments lint
would mark a false positive.

This exempts overloaded (non-primitive) assign ops from being treated as
assignments (they are method calls).

The previous compile-fail tests that ensure x += 1 can trigger for
primitive types continue to pass. Added a representative test for the
"view" indirection.

df9e173353 test: Clean up alloc_jemalloc usage in tests
Right now there's just a smattering of `// ignore-foo` platforms which is ever
expanding as new ones are added. Instead switch to only running these tests on
Linux/OSX and then use a guaranteed-to-work but not-as-well-tested alternative
on other platforms.

01a2a7f991 rustc: Add an i586-pc-windows-msvc target
Similarly to #31629 where an i586-unknown-linux-gnu target was added, there is
sometimes a desire to compile for x86 Windows as well where SSE2 is disabled.
This commit mirrors the i586-unknown-linux-gnu target and simply adds a variant
for Windows as well.

This is motivated by a recent [Gecko bug][ff] where crashes were seen on 32-bit
Windows due to users having CPUs that don't support SSE2 instructions. It was
requested that we could have non-SSE2 builds of the standard library available
so they could continue to use vanilla releases and nightlies.
