This will make sure that system files that rust binaries depend on in Windows get packaged into stage0 snapshots as well as into Windows installer.
Currently these include `libgcc_s_dw2-1.dll`, `libstdc++-6.dll` and `libpthread-2.dll`. Note that the latter will need to be changed to `pthreadGC2.dll` once Windows build bots get upgraded to mingw 4.0

This fixes a problem with paragraph fills: hitting M-q on a single-line-style (`//`) comment with code immediately before or after it would try to fill the code as part of the paragraph too.
This is broken, and results in poor performance due to the undefined
behaviour in the LLVM IR. LLVM's `mergefunc` is a *much* better way of
doing this since it merges based on the equality of the bytecode.
For example, consider `std::repr`. It generates different code per
type, but is not included in the type bounds of generics.
The `mergefunc` pass works for most of our code but currently hits an
assert on libstd. It is receiving attention upstream so it will be
ready soon, but I don't think removing this broken code should wait any
longer. I've opened #9536 about enabling it by default.

This works by adding this directory to GCC include search path before mingw system headers directories,
so we can intercept their inclusions and add missing definitions without having to modify files in mingw/include.
The trait will keep the `Iterator` naming, but a more concise module
name makes using the free functions less verbose. The module will define
iterables in addition to iterators, as it deals with iteration in
general.
I added a few and removed a few and corrected a couple, all with
reference to the prelude. It ends up a slightly arbitrary decision
precisely what ends up in and what doesn't, unfortunately.
- Remove highlighting of ``L"..."`` (obsolete syntax)
- Remove backslash at end of line being a line continuation always
(obsolete syntax; this only affects comments, actually)
- Add highlighting for backslash at end of line and leading whitespace
on the following line inside a string (a genuine line continuation)
`default-tab-width` is standardly 8, but most programmers and style guides prefer an indentation width smaller than that. Rust itself uses 4 space indents. Most other Emacs modes define the indentation width as 4 or 2 spaces, independently of the width of a Tab character. Depending on `default-tab-width` makes especially little sense for rust-mode because it sets `indent-tabs-mode` to `nil`.
