Auto merge of #85743 - bjorn3:sync_cg_clif-2021-05-27, r=bjorn3

Sync rustc_codegen_cranelift

The main highlight this sync is the removal of several dependencies, making compilation of cg_clif itself faster. There have also been a couple of new features like `#[link_section]` now supporting different segments for Mach-O binaries (thanks `@eggyal!)` and the `imported_main` feature, which is currently unstable.

r? `@ghost`
