Fix soundness bug described in #29859
This is an attempt at fixing the problems described in #29859 based on an IRC conversation between @nikomatsakis and I today. I'm waiting on a full build to come back, otherwise both tests trigger the correct error.
Removing the extraneous not_equal implementation for slices
Happened to stumble upon this one awhile back. Seemed a bit silly to have both the equals and not equals implementation when they're so similar.
macros: stackless expansion
After this PR, macro expansion cannot overflow the stack unless the expanded crate is too deep to fold.
Everything but the stackless placeholder expansion commit is also groundwork for macro modularization.

rustbuild: per target musl-root
config.toml now accepts a target.$TARGET.musl-root key that lets you
override the "build" musl-root value, which is set via the --musl-root
flag or via the build.musl-root key.
With this change, it's now possible to compile std for several musl
targets at once. Here's are the sample commands to do such thing:
```
$ configure \
--enable-rustbuild \
--target=x86_64-unknown-linux-musl,arm-unknown-linux-musleabi \
--musl-root=/musl/x86_64-unknown-linux-musl/
$ edit config.toml && tail config.toml
[target.arm-unknown-linux-musleabi]
musl-root = "/x-tools/arm-unknown-linux-musleabi/arm-unknown-linux-musleabi/sysroot/usr"
$ make
```
r? @alexcrichton
With this we should be able to start producing releases of std for arm musl targets
rustdoc: Filter more incorrect methods inherited through Deref
Old code filtered out only static methods. This code also excludes &mut self methods if there is no DerefMut implementation.
Fixes#35169
resolve: Suggest `use self` when import resolves
Improves errors messages by replacing "Maybe a missing `extern crate`" messages
with "Did you mean `self::...`" when the `self` import would succeed.
Fixes#34191.
Thank you for the help @jseyfried!
Fix "field is never used" warning to take unions into account
When compiling code containing a union with an unused field, rustc says
"struct field is never used".
Rather than saying "struct or union", or adding logic to determine the
type of the item, just change the message to "field is never used",
dropping the "struct".
Update tests accordingly.
incr. comp.: Take spans into account for ICH
This PR makes the ICH (incr. comp. hash) take spans into account when debuginfo is enabled.
A side-effect of this is that the SVH (which is based on the ICHs of all items in the crate) becomes sensitive to the tiniest change in a code base if debuginfo is enabled. Since we are not trying to model ABI compatibility via the SVH anymore (this is done via the crate disambiguator now), this should be not be a problem.
Fixes#33888.
Fixes#32753.
Updated E0559 to new format
Refactored a method that printed one suggested field name,
into a method that returns an `Option` of a suggestion
(Updated test cases accordingly)

rustdoc: Fix associated consts in search results
Associated consts can appear in none trait impls so need to be treated
like methods when generating the search index.
Fixes#36031
