This implements parts of the changes to `Result` and `Option` I proposed and discussed in this thread: https://mail.mozilla.org/pipermail/rust-dev/2013-November/006254.html
This PR includes:
- Adding `ok()` and `err()` option adapters for both `Result` variants.
- Removing `get_ref`, `expect` and iterator constructors for `Result`, as they are reachable with the variant adapters.
- Removing `Result`s `ToStr` bound on the error type because of composability issues. (See https://mail.mozilla.org/pipermail/rust-dev/2013-November/006283.html)
- Some warning cleanups
In order to keep up to date with changes to the libraries that `llvm-config`
spits out, the dependencies to the LLVM are a dynamically generated rust file.
This file is now automatically updated whenever LLVM is updated to get kept
up-to-date.
At the same time, this cleans out some old cruft which isn't necessary in the
makefiles in terms of dependencies.

This upgrades LLVM in order to make progress on #10708, and it's also been awhile since we last upgraded!
The contentious point of this upgrade is that all JIT support has been removed because LLVM is changing it and we're not keeping up with it.
as recommended by @huonw on this PR https://github.com/mozilla/rust/pull/10711 , I removed intermediate step that generates a string instead of directly writing to Writer without generating intermediate string.
Fixes#10565.
`'self` is still allowed for the moment, as it is used everywhere in the codebase. And I'm not sure if it still has a special meaning currently or not.
The main one removed is rust_upcall_reset_stack_limit (continuation of #10156),
and this also removes the upcall_trace function. The was hidden behind a
`-Z trace` flag, but if you attempt to use this now you'll get a linker error
because there is no implementation of the 'upcall_trace' function. Due to this
no longer working, I decided to remove it entirely from the compiler (I'm also a
little unsure on what it did in the first place).
Make trait lifetime parameters early bound in static fn type. Reasoning for this change is (hopefully) explained well enough in the comment, so I'll not duplicate it here. Fixes#10391.

It's useful to allow users to get at the internal std::rc::comm::Port,
and other such fields, since they implement important traits like
Select.
See [rust-dev] "select on std::comm::Port and different types" at https://mail.mozilla.org/pipermail/rust-dev/2013-November/006735.html for background.
Right now, as pointed out in #8132, it is very easy to introduce a subtle race
in the runtime. I believe that this is the cause of the current flakiness on the
bots.
I have taken the last idea mentioned in that issue which is to use a lock around
descheduling and context switching in order to solve this race.
Closes#8132

LLVM's JIT has been updated numerous times, and we haven't been tracking it at
all. The existing LLVM glue code no longer compiles, and the JIT isn't used for
anything currently.
This also rebases out the FixedStackSegment support which we have added to LLVM.
None of this is still in use by the compiler, and there's no need to keep this
functionality around inside of LLVM.
This is needed to unblock #10708 (where we're tripping an LLVM assertion).
This reverts commit c54427ddfb.
Leave the #[ignores] in that were added to rustpkg tests.

The `integer_decode()` function decodes a float (f32/f64)
into integers containing the mantissa, exponent and sign.
It's needed for `rationalize()` implementation of #9838.
The code got ported from ABCL [1].

I got the permission to use this code for Rust from Peter Graves (the ABCL copyright holder) . If there's any further IP clearance needed, let me know.
This begins a rewrite of some sections the tutorial as an introduction
to concepts through the implementation of a simple data structure. I
think this would be a good way to introduce references, generics, traits
and many other concepts too. For example, the section introducing
alternatives to ownership can demonstrate a persistent list.

This function had type &[u8] -> ~str, i.e. it allocates a string
internally, even though the non-allocating version that take &[u8] ->
&str and ~[u8] -> ~str are all that is necessary in most circumstances.
- Implement comment nesting (the implementation is quite ugly at present
and is not quite correct; note the big comment in that area).
- Highlight invalid escape sequences as errors.
- Fix up various inconsistencies and incorrectnesses in number
highlighting.
- Update prelude items (``std::io::{Buffer, Writer, Reader, Seek}``).
- Highlight the ``proc`` keyword.
- Remove %-formatting sequence highlighting (a relic of old formatting).
- Don't highlight TODO in strings (it's unconventional).
