Remove -Zdep-tasks.

This option is not useful any more, we can use `tracing` and `RUSTC_LOG` to debug the dep-graph.

Bump stdarch submodule and remove special handling for LLVM intrinsics that are no longer needed

Bumps stdarch to pull rust-lang/stdarch#1477, which reimplemented some functions with portable SIMD intrinsics instead of arch specific LLVM intrinsics.

Handling of those LLVM intrinsics is removed from cranelift codegen and miri.

Cleanup and improve `--check-cfg` implementation

This PR removes some indentation in the code, as well as preventing some bugs/misusages and fix a nit in the doc.

Add FileCheck annotations to MIR-opt inlining tests

Part of rust-lang#116971, adds FileCheck annotations to MIR-opt tests in `tests/mir-opt/inline`.

I left out a few (such as `inline_cycle`) where it mentioned that the particular outcome of inlining isn't important, just that the inliner doesn't get stuck in an infinite loop.

Parse rustc version at compile time

This PR eliminates a couple awkward codepaths where it was not clear how the compiler should proceed if its own version number is incomprehensible.

https://github.com/rust-lang/rust/blob/dab715641e96a61a534587fda9de1128b75b34dc/src/tools/clippy/clippy_utils/src/qualify_min_const_fn.rs#L385

https://github.com/rust-lang/rust/blob/dab715641e96a61a534587fda9de1128b75b34dc/compiler/rustc_attr/src/builtin.rs#L630

We can guarantee that every compiled rustc comes with a working version number, so the ICE codepaths above shouldn't need to be written.
