Rollup merge of #141945 - nnethercote:rm-Path-is_ident, r=compiler-errors 
Remove `Path::is_ident`.

It checks that a path has a single segment that matches the given symbol, and that there are zero generic arguments. It has a single use.

We also have `impl PartialEq<Symbol> for Path` which does exactly the same thing *except* it doesn't check for zero generic arguments, which seems like an oversight. It has numerous uses.

This commit removes `Path::is_ident`, adds a test for zero generic arguments to `PartialEq<Symbol> for Path`, and changes the single use of `is_ident` to instead use `==`.

README.md

The rustc_ast crate contains those things concerned purely with syntax – that is, the AST ("abstract syntax tree"), along with some definitions for tokens and token streams, data structures/traits for mutating ASTs, and shared definitions for other AST-related parts of the compiler (like the lexer and macro-expansion).

For more information about how these things work in rustc, see the rustc dev guide:
