Upstream LLVM has changed slightly such that our PassWrapper.cpp no longer
comiles (travis errors). This updates the bundled LLVM to the latest nightly
which will hopefully fix the travis errors we're seeing.
The printing of the error message on stack overflow had two sometimes false
assumptions previously. The first is that a local task was always available (it
called Local::take) and the second is that it used println! instead of
manually writing.
The first assumption isn't necessarily true because while stack overflow will
likely only be detected in situations that a local task is available, it's not
guaranteed to always be in TLS. For example, during a println! call a task
may be blocking, causing it to be unavailable. By using Local::try_take(), we
can be resilient against these occurrences.
The second assumption could lead to odd behavior because the stdout logger can
be overwritten to run arbitrary code. Currently this should be possible, but the
utility is much diminished because a stack overflow translates to an abort()
instead of a failure.
This updates a number of ignore-test tests, and removes a few completely
outdated tests due to the feature being tested no longer being supported.
This brings a number of bench/shootout tests up to date so they're compiling
again. I make no claims to the performance of these benchmarks, it's just nice
to not have bitrotted code.

Apparently weak linkage and dlopen aren't quite working out for applications
like servo on android. There appears to be a bug or two in how android loads
dynamic libraries and for some reason libservo.so isn't being found.
As a temporary solution, add an extern "C" function to libstd which can be
called if you have a handle to the crate map manually. When crawling the crate
map, we then check this manual symbol before falling back to the old solutions.

- "Lending an immutable pointer" might be confusing. It was not discussed why borrowed pointers are immutable in the first place.
- Make it clear that the borrowed pointers are immutable even if the variable was declared with `mut`.
- Make it clear that we cannot even assign anything to the variable while its value is being borrowed.

This patch series does a couple things:
* replaces manual `Hash` implementations with `#[deriving(Hash)]`
* adds `Hash` back to `std::prelude`
* minor cleanup of whitespace and variable names.

In its first pass, namely gather_loans, the borrow checker tracks the
initialization sites among other things it does. It does so for let
bindings with initializers but not for bindings in match arms, which are
effectively also assignments. This patch does that for borrow checker.
Closes#12452.
The by-value argument is a copy that is only valid for the duration of
the function call, therefore keeping any pointer to it that outlives the
call is illegal.
They are still are not completely correct, since it does not handle
graphemes at all, just codepoints, but at least it handles the common
case correctly.
The calculation was previously very wrong (rather than just a little bit
wrong): it wasn't accounting for the fact that every character is 1
byte, and so multibyte characters were pretending to be zero width.

file.
Previously multibyte UTF-8 chars were being recorded as byte offsets
from the start of the file, and then later compared against global byte
positions, resulting in the compiler possibly thinking it had a byte
position pointing inside a multibyte character, if there were multibyte
characters in any non-crate files. (Although, sometimes the byte offsets
line up just right to not ICE, but that was a coincidence.)

`.reserve_exact` can cause pathological O(n^2) behaviour, so providing a
`.reserve` that ensures that capacity doubles (if you step 1, 2, ..., n)
is more efficient.

This commit implements a layman's version of realpath() for metadata::loader to

Don't try to match line comments inside of a comment block. That makes
no sense and can highlight differently for people who override their
highlights.
Similarly, don't match a doc-comment inside of a comment block. It
shouldn't be highlighted differently unless it's actually a doc-comment
(and nested comments are obviously not doc comments).
Fixes#12307.
Build metadata is already excluded from precedence checking in line with
the spec. For consistency and providing strict total ordering for
Version, build metadata should also be ignored in Eq impl.

tidy has some limitations (e.g. the "checked in binaries" check doesn't
and can't actually check git), and so it's useful to run tests without
running tidy occasionally.
