Sync rustc_codegen_cranelift

The highlight of this sync are two JIT mode improvements. The first is that it is now possible to use JIT mode when using `-Zcodegen-backend` instead of the custom driver using `-Cllvm-args=mode=jit`. The second one is a new JIT mode that lazily compiles functions when they are called the first time: https://github.com/bjorn3/rustc_codegen_cranelift/pull/1120

In addition this includes a few small runtime performance improvements and various fixes for rustc changes that didn't cause compilation to fail.
