this introduces a DropAndReplace terminator as a fix to #30380. That terminator
is suppsoed to be translated by desugaring during drop elaboration, which is
not implemented in this commit, so this breaks `-Z orbit` temporarily.
Use Docker for Travis
The primary motivtion is to use system LLVM from ubuntu.com, instead of llvm.org.
Travis provides two environments: Ubuntu 12.04 LTS aka precise by default, and Ubuntu 14.04 LTS aka trusty if you specify dist: trusty. According to travis-ci/travis-ci#5821, Ubuntu 16.04 LTS aka xenial is unlikely to be available this year, and Travis recommends to use Docker.
LLVM 3.7 binary for 12.04 and 14.04 is not available from ubuntu.com, that's why we used llvm.org. But LLVM 3.7 binary for 16.04 is available from ubuntu.com, and we can use Docker to run on 16.04.
Fix#34009.
Rewrite variadic-ffi pass to use test helper
The sprintf used in this test previously isn’t available on some versions of MSVC.
Fixes#32305

Hopefully this pacifies the 32bit windows. Apparently there’s an ABI out there that not only allows
non-64 bit variadic arguments, but also has differing ABI for them!
Good thing all variadic functions are unsafe.
We need to traverse stripped modules to generate redirect pages, but we shouldn't generate
anything else for them.
This now renders the file contents to a Vec before writing it to a file in one go. I think
that's probably a better strategy anyway.
The only applies to pthread mutexes. We solve this by creating the
mutex with the PTHREAD_MUTEX_NORMAL type, which guarantees that
re-locking from the same thread will deadlock.
Fix a few links in the book
Links to directories and direct links to doc.rust-lang.org don't work properly
when viewing the docs offline so fix them.

Restore original meaning of std::fs::read_dir's example changed in #33958
`DirEntry.file_type().is_dir()` will not follow symlinks, but the original example (`fs::metadata(&path).is_dir()`) does. Therefore the change in #33958 introduced a subtle difference that now it won't enter linked folders. To preserve the same behavior, we use `Path::is_dir()` instead, which does follow symlink.
(See discussion in the previous PR for detail.)
Implement split_off for BTreeMap and BTreeSet (RFC 509)
Fixes#19986 and refactors common with append methods.
It splits the tree with O(log n) operations and then calculates sizes by traversing the lower one.

The previous version of the chapter covered a lot of ground, but was a little
meandering and hard to follow at times. This draft is intended to be clearer
and more direct, while still providing the same information as the previous
version.
