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).

This registers new snapshots after the landing of #10528, and then goes on to tweak the build process to build a monolithic `rustc` binary for use in future snapshots. This mainly involved dropping the dynamic dependency on `librustllvm`, so that's now built as a static library (with a dynamically generated rust file listing LLVM dependencies).
This currently doesn't actually make the snapshot any smaller (24MB => 23MB), but I noticed that the executable has 11MB of metadata so once progress is made on #10740 we should have a much smaller snapshot.
There's not really a super-compelling reason to distribute just a binary because we have all the infrastructure for dealing with a directory structure, but to me it seems "more correct" that a snapshot compiler is just a `rustc` binary.
I've renamed `MutableVector::mut_split(at)` to `MutableVector::mut_split_at(at)` to be coherent with ImmutableVector. As specified in the commit log, The `size_hint` method is not optimal because of #9629.
This method is the mutable version of ImmutableVector::split. It is
a DoubleEndedIterator, making mut_rsplit irrelevent. The size_hint
method is not optimal because of #9629.
At the same time, clarify *split* iterator doc.
* Don't flag any address_insignificant statics as reachable because the whole
point of the address_insignificant optimization is that the static is not
reachable. Additionally, there's no need for it to be reachable because LLVM
optimizes it away.
* Be sure to not leak external node ids into our reachable set, this can
spuriously cause local items to be considered reachable if the node ids just
happen to line up
The section on closure types was missing, so I added one. I'm new to Rust, so there are probably important things to say about closure types that I'm missing here.
I tested the example with the latest Rust nightly.
This wasn't uncovered during testing because the librustrt is available locally
in the build directory (and it needs to be for all the tests to link against it
as well).
Closes#10765
Controversial change: make the constructors safe, but instead mark the
setters and getters as unsafe. This follows the tradition that construction
of *T is safe, but the access is unsafe instead.
