- Added `TraitObject` representation to `std::raw`.
- Added doc to `std::raw`.
- Removed `Any::as_void_ptr()` and `Any::as_mut_void_ptr()`
  methods as they are uneccessary now after the removal of
  headers on owned boxes. This reduces the number of virtual calls needed from 2 to 1.
- Made the `..Ext` implementations work directly with the repr of
  a trait object.
- Removed `Any`-related traits from the prelude.
- Added bench.

While we are not yet ready for compiler i18n, this also keeps the error handling code clean. The set of altered error messages was obtained by grepping for `"s"` and `(s)`, so there might be some missing messages.

syntax: make match arms store the expr directly.

Previously `ast::Arm` was always storing a single `ast::Expr` wrapped in an
`ast::Block` (for historical reasons, AIUI), so we might as just store
that expr directly.

Closes #3085.

This should fix the travis builds.

std: add reserve_additional and an Extendable impl to Vec.

This should get us a passing snapshot again.

The incompatibility of rust-mode with global-whitespace-mode warned
about in the README was actually fixed by commit 581b3db3.  Remove the
warning from the README and close #3994.

These tests are failing on the snap builders, and are now tagged with a FIXME.

cc #12102

A couple of syntax extensions manually expanded expressions, but it
wasn't done universally, most noticably inside of asm!().

There's also a bit of random cleanup.

According to `/etc/terminfo/README`,
```
This directory is for system-local terminfo descriptions. By default,
ncurses will search ${HOME}/.terminfo first, then /etc/terminfo (this
directory), then /lib/terminfo, and last not least /usr/share/terminfo.

This commit let librustc automatically pickup LDFLAGS dependencies
inherited from LLVM, which may otherwise result in undefined
references to external symbols under certain linking environment.

A symptom of this issue is eg. a failure when trying to link against
librustc (due to unresolved ffi_* symbols), while using a system-wide
LLVM.

Indirect dependencies should now be picked up through the
autogenerated llvmdeps.rs instead.

Macro definitions are just their raw source code, and so should be
highlighted where possible. Also, $ident non-terminal substitutions are
special, and so are worthy of a little special treatment.

When the metadata format changes, old libraries often cause librustc to abort
when reading their metadata. This should all change with the introduction of SVH
markers, but the loader for crates should gracefully handle libraries without
SVH markers still.

This commit adds support for tripping fewer assertions when loading libraries by
using maybe_get_doc when initially parsing metadata. It's still possible for
some libraries to fall through the cracks, but this should deal with a fairly
large number of them up front.
