Stabilize `transmute` in constants and statics but not const fn
cc #53605 (leaving issue open so we can add `transmute` to `const fn` later)
Previous attempt: #64011

Update rust-installer to latest version
This pulls in a fix for the install script on some tr(1) implementations,
as well as an update to use `anyhow` instead of `failure` for error
handling.
Avoid "blacklist"
Other terms are more inclusive and precise.
Clippy still has a lint named "blacklisted-name", but renaming it would
be a breaking change, so is left for future work.
The target configuration option "abi-blacklist" has been depreciated and
renamed to "unsupported-abis". The old name continues to work.

Eliminate confusing "globals" terminology.
There are some structures that are called "globals", but are they global
to a compilation session, and not truly global. I have always found this
highly confusing, so this commit renames them as "session globals" and
adds a comment explaining things.
Also, the commit fixes an unnecessary nesting of `set()` calls
`src/librustc_errors/json/tests.rs`

Add rust-analyzer to the build manifest
Does not die locally, produces `rust-analyzer-0.1.0-dev-x86_64-unknown-linux-gnu.tar.gz.sha256` and add something about rust-analyzer to some `.toml` file. Seems like a success?
typeck: adding type information to projection
This commit modifies the Place as follow:
* remove 'ty' from ProjectionKind
* add type information into to Projection
* replace 'ty' in Place with 'base_ty'
* introduce 'ty()' in `Place` to return the final type of the `Place`
* introduce `ty_before_projection()` in `Place` to return the type of
a `Place` before i'th projection is applied
Closes https://github.com/rust-lang/project-rfc-2229/issues/5
ship rust analyzer
This successfully builds rust-analyzer as a part of rust repo. I haven't yet added required changes to dist.rs -- seems like I just have to copy-paste quite a bit of code I don't really understand :-)
The current plan is that submodule tracks the `release` branch of
rust-analyzer, which is updated once a week.
rust-analyzer is a workspace (with a virtual manifest), the actual
binary is provide by `crates/rust-analyzer` package.
Note that we intentionally don't add rust-analyzer to `Kind::Test`,
for two reasons.
*First*, at the moment rust-analyzer's test suite does a couple of
things which might not work in the context of rust repository. For
example, it shells out directly to `rustup` and `rustfmt`. So, making
this work requires non-trivial efforts.
*Second*, it seems unlikely that running tests in rust-lang/rust repo
would provide any additional guarantees. rust-analyzer builds with
stable and does not depend on the specifics of the compiler, so
changes to compiler can't break ra, unless they break stability
guarantee. Additionally, rust-analyzer itself is gated on bors, so we
are pretty confident that test suite passes.

Record span of `const` kw in GenericParamKind
Context: this is needed for a fix of https://github.com/rust-lang/rustfmt/issues/4263,
which currently records the span of a const generic param incorrectly
because the location of the `const` kw is not known.
I am not sure how to add tests for this; any guidance in how to do so
would be appreciated 🙂
