Set correct segment from #[link_section] for MachO
This is one step towards separating the linking code from codegen backends
This removes all the byteorder and thiserror dependencies. This results in no proc macros being necessary anymore.
This commit implements both the native linking modifiers infrastructure as well as an initial attempt at the individual modifiers from the RFC. It also introduces a feature flag for the general syntax along with individual feature flags for each modifier.
Git seems to not be able to handle it in some cases. Thanks to @vramana for reporting this on Zulip.

rustc_driver cleanup Best reviewed one commit at a time.
This is necessary to support the cpufeatures crate Fixes rust-lang#1173
Remove CrateNum parameter for queries that only work on local crate The pervasive `CrateNum` parameter is a remnant of the multi-crate rustc idea. Using `()` as query key in those cases avoids having to worry about the validity of the query key.
- make Allocation API offset-based (no more Pointer) - make Memory API higher-level (combine checking for access and getting access into one operation)

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 theimported_mainfeature, which is currently unstable.r? @ghost
