We currently have a non-additive feature, "force-soft-floats", and we will need to gain another "no-f16-f128". This makes `cfg` usage in code somewhat confusing and redundant. Use `build.rs` to figure out if "unstable-intrinsics" is enabled while "force-soft-floats" is not enabled and if so, emit a cfg `intrinsics_enabled`. This is cleaner to use and should make adding more features easier to reason about. Also use this as an opportunity to eliminate the build.rs from the compiler-builtins test crate, replaced with the `[lints]` table in Cargo.toml.
