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: bjorn3/rustc_codegen_cranelift#1120
In addition this includes a few small runtime performance improvements and various fixes for rustc changes that didn't cause compilation to fail.
