Rollup merge of #121841 - tgross35:f16-f128-step2-intrinsics, r=compiler-errors 
`f16` and `f128` step 2: intrinsics

Continuation of https://github.com/rust-lang/rust/pull/121728, another portion of https://github.com/rust-lang/rust/pull/114607.

This PR adds `f16` and `f128` intrinsics, and hooks them up to both HIR and LLVM. This is all still unexposed to the frontend, which will probably be the next step. Also update itanium mangling per `@rcvalle's` in https://github.com/rust-lang/rust/pull/121728/files#r1506570300, and fix a typo from step 1.

Once these types are usable in code, I will add the codegen tests from #114607 (codegen is passing on that branch)

This does add more `unimplemented!`s to Clippy, but I still don't think we can do better until library support is added.

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:
