Instead of requesting the region maps for the entire crate, request for
a given item etc. Several bits of code were modified to take
`&RegionMaps` as input (e.g., the `resolve_regions_and_report_errors()`
function). I am not totally happy with this setup -- I *think* I'd
rather have the region maps be part of typeck tables -- but at least the
`RegionMaps` works in a "parallel" way to `FreeRegionMap`, so it's not
too bad. Given that I expect a lot of this code to go away with NLL, I
didn't want to invest *too* much energy tweaking it.
refactor the handling of lvalue ops
I think I got the code into a "mostly sane" situation.
Fixes#41604.
beta-nominating because fixes regression in #41578. I think I can do a smaller fix, but the previous code is too fragile.

process:exit -> process::exit in mem::forget docs
The documentation in mem::forget says "...or call `process:exit`..."
instead of `process::exit`.

Fix links in RELEASES.md for 1.10.0 through 1.12.0
Many links in this series have the `[link text]` and `(url)` on separate
lines, which doesn't get correctly interpreted in markdown. Or maybe it
once did, but it doesn't now. This patch joins the lines together.
Here is the content rendered [before](2971d491b9/RELEASES.md (version-1120-2016-09-29)) and [after](e8c4b7af21/RELEASES.md (version-1120-2016-09-29)).
Add a distcheck for rust-src completeness
This is for the last commit of #41546. For some reason, @bors only saw the first two commits, and wouldn't approve the last even when explicitly directed so.

reduce stack requirements for floating-point formatting
Doing this speeds up float formatting by ~10% or so, and also makes the formatting code more suitable for embedded environments where stack space is at a premium.
FromIterator and Extend Cow for String
This is a quick draft to start working on [#41351](https://github.com/rust-lang/rust/issues/41351).
I don't think I got the stable attributes correct, but it is good enuf to start a conversation.
query for def_span
Resolves `fn def_span(&self, sess: &Session, def: DefId) -> Span;` of #41417.
I had to change the query name to `def_sess_span` since `ty::TyCtxt` already has a method `def_span` implemented.
This also will probably have merge conflicts with #41534 but I will resolves those once it's merged and wanted to start a code review on this one now.

Update stage0 bootstrap compiler
We've got a freshly minted beta compiler, let's update to use that on nightly!
This has a few other changes associated with it as well
* A bump to the rustc version number (to 1.19.0)
* Movement of the `cargo` and `rls` submodules to their "proper" location in
`src/tools/{cargo,rls}`. Now that Cargo workspaces support the `exclude`
option this can work.
* Updates of the `cargo` and `rls` submodules to their master branches.
* Tweak to the `src/stage0.txt` format to be more amenable for Cargo version
numbers. On the beta channel Cargo will bootstrap from a different version
than rustc (e.g. the version numbers are different), so we need different
configuration for this.
* Addition of `dev` as a readable key in the `src/stage0.txt` format. If present
then stage0 compilers are downloaded from `dev-static.rust-lang.org` instead
of `static.rust-lang.org`. This is added to accomodate our updated release
process with Travis and AppVeyor.

Checker:: Execute levenshtein before other context checking
As explain [here]() i think it's better to check for a miss typing before checking context dependent help.
```rust
struct Handle {}
struct Something {
handle: Handle
}
fn main() {
let handle: Handle = Handle {};
let s: Something = Something {
// Checker detect an error and propose a solution with `Handle { /* ... */ }`
// but it's a miss typing of `handle`
handle: Handle
};
}
```

use diff crate for compile-fail test diagnostics #41474
Hello!
This fixes#41474
We were using a custom implementation to dump the differences between expected and actual outputs of compile-fail tests.
I removed this internal implementation and added `diff` crate as a new dependency to `compile-fail`.
Again, huge thanks to @nikomatsakis for guiding.
Disable ref hint for pattern in let and adding ui tests #40402
A fix to #40402
The `to prevent move, use ref e or ref mut e ` has been disabled.
```
fn main() {
let v = vec![String::from("oh no")];
let e = v[0];
}
```
now gives
```
error[E0507]: cannot move out of indexed content
--> example.rs:4:13
|
4 | let e = v[0];
| ^^^^ cannot move out of indexed content
error: aborting due to previous error
```
I have added ui tests for the same and also modified a compile-fail test.
Replaces the llvm-c exposed LLVMRelocMode, which does not include all
relocation model variants, with a LLVMRustRelocMode modeled after
LLVMRustCodeMode.
The comments for flt2dec::to_shortest_str says that we only need a slice
of length 5 for the parts array. Initializing a 16-part array is just
wasted effort and wasted stack space. Other functions in the flt2dec
module have similar comments, so we adjust the parts arrays passed to
those functions accordingly.
For the two major entry points for float formatting, we split the exact
case and the shortest cases into separate functions. We mark the
separate functions as #[inline(never) so the exact cases won't bloat
stack space in their callers unnecessarily. The shortest cases are
marked so for similar reasons.
Fixes#41234.
We have benchmarks for the floating-point formatting algorithms
themselves, but not for the surrounding machinery like Formatter and
translating to the flt2dec::Part slices.

make *most* maps private
Currently we access the `DepTrackingMap` fields directly rather than using the query accessors. This seems bad. This branch removes several such uses, but not all, and extends the macro so that queries can hide their maps (so we can prevent regressions). The extension to the macro is kind of ugly :/ but couldn't find a simple way to do it otherwise (I guess I could use a nested macro...). Anyway I figure it's only temporary.

travis: Parallelize tests on Android
Currently our slowest test suite on android, run-pass, takes over 5 times longer
than the x86_64 component (~400 -> ~2200s). Typically QEMU emulation does indeed
add overhead, but not 5x for this kind of workload. One of the slowest parts of
the Android process is that *compilation* happens serially. Tests themselves
need to run single-threaded on the emulator (due to how the test harness works)
and this forces the compiles themselves to be single threaded.
Now Travis gives us more than one core per machine, so it'd be much better if we
could take advantage of them! The emulator itself is still fundamentally
single-threaded, but we should see a nice speedup by sending binaries for it to
run much more quickly.
It turns out that we've already got all the toos to do this in-tree. The
qemu-test-{server,client} that are in use for the ARM Linux testing are a
perfect match for the Android emulator. This commit migrates the custom adb
management code in compiletest/rustbuild to the same qemu-test-{server,client}
implementation that ARM Linux uses.
This allows us to lift the parallelism restriction on the compiletest test
suites, namely run-pass. Consequently although we'll still basically run the
tests themselves in single threaded mode we'll be able to compile all of them in
parallel, keeping the pipeline much more full hopefully and using more cores for
the work at hand. Additionally the architecture here should be a bit speedier as
it should have less overhead than adb which is a whole new process on both the
host and the emulator!
Locally on an 8 core machine I've seen the run-pass test suite speed up from
taking nearly an hour to only taking 5 minutes. I don't think we'll see quite a
drastic speedup on Travis but I'm hoping this change can place the Android tests
well below 2 hours instead of just above 2 hours.
Because the client/server here are now repurposed for more than just QEMU,
they've been renamed to `remote-test-{server,client}`.
Note that this PR does not currently modify how debuginfo tests are executed on
Android. While parallelizable it wouldn't be quite as easy, so that's left to
another day. Thankfull that test suite is much smaller than the run-pass test
suite.
