Remove save-analysis. 

Most tests involving save-analysis were removed, but I kept a few where
the `-Zsave-analysis` was an add-on to the main thing being tested,
rather than the main thing being tested.

For `x.py install`, the `rust-analysis` target has been removed.

For `x.py dist`, the `rust-analysis` target has been kept in a
degenerate form: it just produces a single file `reduced.json`
indicating that save-analysis has been removed. This is necessary for
rustup to keep working.

Closes #43606.

// A signature is a string representation of an item's type signature, excluding
// any body. It also includes ids for any defs or refs in the signature. For
// example:
//
// ```
// fn foo(x: String) {
// println!("{}", x);
// }
// ```
// The signature string is something like "fn foo(x: String) {}" and the signature
// will have defs for `foo` and `x` and a ref for `String`.
//
// All signature text should parse in the correct context (i.e., in a module or
// impl, etc.). Clients may want to trim trailing `{}` or `;`. The text of a
// signature is not guaranteed to be stable (it may improve or change as the
// syntax changes, or whitespace or punctuation may change). It is also likely
// not to be pretty - no attempt is made to prettify the text. It is recommended
// that clients run the text through Rustfmt.
//
// This module generates Signatures for items by walking the AST and looking up
// references.
//
// Signatures do not include visibility info. I'm not sure if this is a feature
// or an omission (FIXME).
//
// FIXME where clauses need implementing, defs/refs in generics are mostly missing.
