Before PR #32202, check_match tended to report bogus errors or ICE
when encountering a pattern that split a literal, e.g.
```Rust
match foo {
"bar" => {},
&_ => {}
}
```
That PR fixed these issues, but trans::_match generates bad code
when it encounters these matches. MIR trans has that fixed, but
it is waiting for 6 weeks in beta. Report an error when encountering
these instead.
Fixes issue #35044.

We used to put the flag on the `InferCtxt`.
|
|
We used to write a temporary closure kind into the inference table, but
this could lead to obligations being incorrectled resolved before
inference had completed. This result could then be cached, leading to
further trouble. This patch avoids writing any closure kind until the
computation is complete.
Fixes #34349.

Move LLVM cleanup so modules are accessible during `after_llvm` phase
Fix for #34432. Also added a new phase controller `after_compilation_done` that gets called at the very end (i.e. after linking) at the suggestion of @nrc. The added test will segfault if the modules get deallocated too early, so it ensures the LLVM is not prematurely cleaned up.

Issue #34076: Removing reference to removed path.prefix() function
In the documentation for `std::path::Path`, there is a [reference](https://doc.rust-lang.org/std/path/struct.Path.html#method.is_absolute) to the `path.prefix()` function which has since been removed. The offending reference is now also removed.
First pull request, feedback welcome!

prefer `if let` to match with `None => {}` arm in some places
This is a spiritual succesor to #34268 / 8531d581, in which we replaced a
number of matches of None to the unit value with `if let` conditionals
where it was judged that this made for clearer/simpler code (as would be
recommended by Manishearth/rust-clippy's `single_match` lint). The same
rationale applies to matches of None to the empty block.

Remove redundant `CompileController` entry points
Remove the `after_expand` and `after_write_deps` `CompileController` entry points.
The only things that separate these entry points from `after_hir_lowering` are dep-info generation and HIR map construction, neither of which is computationally intensive or has the potential to error.

std: Stabilize APIs for the 1.11.0 release
Although the set of APIs being stabilized this release is relatively small, the
trains keep going! Listed below are the APIs in the standard library which have
either transitioned from unstable to stable or those from unstable to
deprecated.
Stable
* `BTreeMap::{append, split_off}`
* `BTreeSet::{append, split_off}`
* `Cell::get_mut`
* `RefCell::get_mut`
* `BinaryHeap::append`
* `{f32, f64}::{to_degrees, to_radians}` - libcore stabilizations mirroring past
libstd stabilizations
* `Iterator::sum`
* `Iterator::product`
Deprecated
* `{f32, f64}::next_after`
* `{f32, f64}::integer_decode`
* `{f32, f64}::ldexp`
* `{f32, f64}::frexp`
* `num::One`
* `num::Zero`
Added APIs (all unstable)
* `iter::Sum`
* `iter::Product`
* `iter::Step` - a few methods were added to accomodate deprecation of One/Zero
Removed APIs
* `From<Range<T>> for RangeInclusive<T>` - everything about `RangeInclusive` is
unstable
Closes #27739
Closes #27752
Closes #32526
Closes #33444
Closes #34152
cc #34529 (new tracking issue)

Book: Small grammatical and stylistic edits to book
I've been reading [the book](https://doc.rust-lang.org/book/) and noticed a few small grammatical and stylistic issues which I've rolled into this pull request.
I'm not sure if I should do so many small, unrelated edits in a single pull request but it seems like a lot of overhead for each small edit. Maybe one commit per edit but one pull request per file/section? Feedback is very much appreciated as this is my first pull request ever!

Support more python 2.7 versions in bootstrap.py
It seems python broke compatability between 2.7.9 and 2.7.12 as on the former a WindowsError was raised while on the latter a subprocess.CalledProcessError was raised while testing for the existence of uname.
As a WindowsError being thrown obviously indicates we're running on windows, this should probably be accepted too.

fail obligations that depend on erroring obligations
Fix a bug where an obligation that depend on an erroring obligation would
be regarded as successful, leading to global cache pollution and random
lossage.
Fixes #33723.
Fixes #34503.
r? @eddyb since @nikomatsakis is on vacation
beta-nominating because of the massive lossage potential (e.g. with `Copy` this could lead to random memory leaks), plus this is a regression.

Disallow constants and statics from having unsized types.
This is a `[breaking-change]` which fixes #34390 by banning unsized `const` and `static`, e.g.:
```rust
const A: [i32] = *(&[0, 1, 2] as &[i32]);
static B: str = *"foo";
```
This was not intentionally allowed, and other than for `static` since some versions ago, it ICE'd.
If you've been taking advantage of this with `static`, you should be able to just use references instead.

Make the metadata lock more robust
Fixes #33778 and friends.
I also needed to add a metadata encoding version to rlibs, as they did not have it before. To keep it backwards-compatible, I added 4 zeroes to the start of the metadata, which are treated as an empty length field by older rustcs.
r? @alexcrichton

previously, only .so files included a metadata encoding version, *outside*
of the zlib compressed area. This adds an encoding version inside the metadata
itself, in both .so and .rlib files.
Fixes #33778.

remove unneeded allow flag
There isn't anything deprecated being used in this function.
This built fine for me locally, but just to be sure, should check Travis.

rustbuild: Implement testing for Android
This commit enhances the rustbuild support for testing Android to the same level
of parity as the makefiles. This involved:
* A new step to copy the standard library and other shared objects to the
emulator. This is injected as a dependency of all test suites for Android.
* Appropriate arguments are now passed through to compiletest to ensure that it
can run tests.
* When testing the standard library the test executables are probed for and
shipped to the emulator to run for each test.
* Fixing compilation of compiler-rt a bit
All support added here is modeled after what's found in the makefiles, just
translating one strategy to another. As an added bonus this commit adds support
for the "check" step to automatically run tests for all targets, and the
"check-target" step now runs all tests for a particular target, automatically
filtering the tests if the target is detected as a cross-compile.
Note that we don't (and probably won't) have a bot which is actually going to
exercise any of this just yet, but all tests have passed locally for me at
least.
