Simplify librustc_errors This is part 2 of the error crate refactor, starting with #34403. In this refactor, I focused on slimming down the error crate to fewer moving parts. As such, I've removed quite a few parts and replaced the with simpler, straight-line code. Specifically, this PR: * Removes BasicEmitter * Remove emit from emitter, leaving emit_struct * Renames emit_struct to emit * Removes CoreEmitter and focuses on a single Emitter * Implements the latest changes to error format RFC (#1644) * Removes (now-unused) code in emitter.rs and snippet.rs * Moves more tests to the UI tester, removing some duplicate tests in the process There is probably more that could be done with some additional refactoring, but this felt like it was getting to a good state. r? @alexcrichton cc: @Manishearth (as there may be breaking changes in stuff I removed/changed)

Null fn lints Adds lints to check for code, that assumes nullable `fn()`. ### Lint examples: `transmute_null_to_fn`: ```rust error: transmuting a known null pointer into a function pointer --> $DIR/transmute_null_to_fn.rs:9:23 | LL | let _: fn() = std::mem::transmute(std::ptr::null::<()>()); | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ this transmute results in undefined behavior | = help: try wrapping your function pointer type in `Option<T>` instead, and using `None` as a null pointer value ``` `fn_null_check`: ```rust error: function pointer assumed to be nullable, even though it isn't --> $DIR/fn_null_check.rs:13:8 | LL | if (fn_ptr as *mut ()).is_null() {} | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | = help: try wrapping your function pointer type in `Option<T>` instead, and using `is_none` to check for null pointer value ``` Closes rust-lang#1644 --- changelog: Improvement: [`transmuting_null`]: Now detects `const` pointers to all types [rust-lang#10099](rust-lang/rust-clippy#10099) changelog: New lint: [`transmute_null_to_fn`] [rust-lang#10099](rust-lang/rust-clippy#10099) changelog: New lint: [`fn_null_check`] [rust-lang#10099](rust-lang/rust-clippy#10099) <!-- changelog_checked (This is just a flag for me, please don't add it manually) -->
