`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. r? `@compiler-errors` cc `@Nilstrieb` `@rustbot` label +T-compiler +F-f16_and_f128 |

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:
