e530829797 Use 'cargo check' to build the sysroot and target crate 
Fixes #1057

Since we are no longer using "cargo rustc", we now use the rustc
arguments passed by Cargo to determine whether we are building a
build dependency, normal dependency, or "target" (final binary or test)
crate.

0a803c9752 Auto merge of #1158 - divergentdave:shim-rename, r=RalfJung 
Add shim for rename

This adds a straightforward shim for rename, which is used by `std::fs::rename`. Testing is included.

As a heads up, I expect one or two merge conflicts between my PRs, since some of them touch the same `use` statements, or add items near the same places. I'll rebase and fix them as they come up.
