Recently we switched from the win32 MinGW toolchain to the pthreads-based
toolchain. We ship `gcc.exe` from this toolchain with the `rust-mingw` package
in the standard distribution but the pthreads version of `gcc.exe` depends on
`libwinpthread-1.dll`. While we're shipping this DLL for the compiler to depend
on we're not shipping it for gcc. As a workaround just copy the dll to gcc.exe
location and don't attempt to share for now.

Didn't get around to removing all public access.
This requires copying out the cycle error to avoid a cyclic borrow.  Is
this a problem? Are there paths where we expect cycles to arise and not
result in errors? (In such cases, we could add a faster way to test for
cycle.)
…-map, r=eddyb

make *most* maps private

Currently we access the `DepTrackingMap` fields directly rather than using the query accessors. This seems bad. This branch removes several such uses, but not all, and extends the macro so that queries can hide their maps (so we can prevent regressions). The extension to the macro is kind of ugly :/ but couldn't find a simple way to do it otherwise (I guess I could use a nested macro...). Anyway I figure it's only temporary.

don't ICE on cross-crate associated const type mismatch

Fixes rust-lang#41549.

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @pnkfelix (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.
