Clarify that VecDeque::swap can panic

The previous documentation mentioned this, but ambiguously used the term "fail".

This clarifies that the function will panic if the index is out of bounds, instead of silently failing and not doing anything.

If there's anything else I can do to improve this PR, I'd be happy to do so! Just saw this when reading through the docs in passing - it was slightly unclear what "fail" meant.

8be132e9d7 Initial diagnostic API for proc-macros.
This commit introduces the ability to create and emit `Diagnostic`
structures from proc-macros, allowing for proc-macro authors to emit
warning, error, note, and help messages just like the compiler does.

8bb29465d0 feature error span on attr. for fn_must_use, SIMD/align, macro reëxport
There were several feature-gated attributes for which the
feature-not-available error spans would point to the item annotated with
the gated attribute, when it would make more sense for the span to point
to the attribute itself: if the attribute is removed, the
function/struct/&c. likely still makes sense and the program will
compile. (Note that we decline to make the analogous change for the
`main`, `start`, and `plugin_registrar` features, for in those cases it
makes sense for the span to implicate the entire function, of which
there is little hope of using without the gated attribute.)

rustbuild: Rewrite the configure script in Python

This commit rewrites our ancient `./configure` script from shell into Python.
The impetus for this change is to remove `config.mk` which is just a vestige of
the old makefile build system at this point. Instead all configuration is now
solely done through `config.toml`.

The python script allows us to more flexibly program (aka we can use loops
easily) and create a `config.toml` which is based off `config.toml.example`.
This way we can preserve comments and munge various values as we see fit.

It is intended that the configure script here is a drop-in replacement for the
previous configure script, no functional change is intended. Also note that the
rationale for this is also because our build system requires Python, so having a
python script a bit earlier shouldn't cause too many problems.

7534f7375b clear out projection subobligations after they are processed
After a projection was processed, its derived subobligations no longer
need any processing when encountered, and can be removed. This improves
the status of #43787.

This is actually complementary to #43938 - that PR fixes selection
caching (and @remram44's example, which "accidentally" worked because of
the buggy projection caching) while this PR fixes projection caching

eb8f2586eb Auto merge of #44060 - taleks:issue-43205, r=arielb1
Fixes issue #43205: ICE in Rvalue::Len evaluation.

- fixes evaluation of array length for zero-sized type referenced by rvalue operand.
- adds test to verify fix.

*Cause of the issue*.

Zero-sized aggregates are handled as operands, not lvalues. Therefore while visiting `Assign` statement by `LocalAnalyser`, `mark_as_lvalue()` is not called for related `Local`. This behaviour is controlled by `rvalue_creates_operand()` method.

As result it causes error later, when rvalue operand is evaluated in `trans_rvalue_operand()` while handling `Rvalue::Len` case. Array length evaluation invokes `trans_lvalue()` which expects referenced `Local` to be value, not operand.

*How it is fixed*.

In certain cases result of `Rvalue::Len` can be evaluated without calling
`trans_lvalue()`. Method `evaluate_array_len()` is introduced to handle length
evaluation for zero-sized types referenced by Locals.

*Some concerns*.

- `trans_lvalue()` has two other entry points in `rvalue.rs`: it is invoked while handling `Rvalue::Ref` and `Rvalue::Discriminant`. There is a chance those may produce the same issue, but I've failed to write a specific test that leads to this.
- `evaluate_array_len()` performs the same check (matches lvalue and `Local`), which is performed again in `trans_lvalue()`. Without changing `trans_lvalue()` signature to make it aware that caller deals with rvalue, it seems there is no cheap solution to avoid this check.

Make unused-extern-crate warn-by-default

Apart from enabling the lint, this pull request also removes existing unused crates in the codebase, and fix some amount of false positives on crates with special purposes.

Now that all false positive issues are closed, it should be possible to make it available to wider users.

Add test for wrong code generation for HashSet creation on arm cpu

This is test for #42918.
To reproduce bug you need machine with arm cpu and compile with optimization.
I tried with rustc 1.19.0-nightly (3d5b8c626 2017-06-09),
if compile test with -C opt-level=3 for target=arm-linux-androideabi
and run on "Qualcomm MSM 8974 arm cpu" then assert fails,
if compile and run with -C opt-level=2 it gives segmentation fault.
So I add `compile-flags: -O`.
With rustc 1.19.0 (0ade33941 2017-07-17) all works fine.

rustbuild: Automatically enable Ninja on MSVC

Discovered in #43767 it turns out the default MSBuild generator in CMake for
whatever reason isn't supporting many of the configuration options we give to
LLVM. To improve the contributor experience automatically enable Ninja if we
find it to ensure that "flavorful" configurations of LLVM work by default in
more situations.

Fix destruction extent lookup during HIR -> HAIR translation

My method for finding the destruction extent, if any, from cbed41a174 (in #39409), was buggy in that it sometimes failed to find an extent that was nonetheless present.

This fixes that, and is cleaner code to boot.
