incr.comp.: Remove ability to produce incr. comp. hashes during metadata export.
This functionality has been superseded by on-import hashing, which can be less conservative and does not require extra infrastructure.

incr.comp.: Some preparatory work for caching more query results.
This PR
* adds and updates some encoding/decoding routines for various query result types so they can be cached later, and
* adds missing `[input]` annotations for a few `DepNode` variants.
The situation around having to explicitly mark dep-nodes/queries as inputs is not really satisfactory. I hope we can find a way of making this more fool-proof in the future.

avoid type-live-for-region obligations on dummy nodes
Type-live-for-region obligations on DUMMY_NODE_ID cause an ICE, and it
turns out that in the few cases they are needed, these obligations are not
needed anyway because they are verified elsewhere.
Fixes#46069.
Beta-nominating because this is a regression for our new beta.

Revert #46360, re-enable macOS dist images.
This PR reverts #46360, which disabled all macOS dist images to workaround travis-ci/travis-ci#8821.
This PR should be merged as soon as the Travis bug has been fixed.
Closes#46357.

Reject '2' as a binary digit in internals of b: number formatting
The `radix!` macro generates an implementation of the private trait `GenericRadix`, and the code replaced changes Binary's implementation to no longer accept '2' as a valid digit to print.
Granted, this code is literally only ever called from another method in this private trait, and that method has logic to never hand a '2' to the printing function. Even given this, the code's there, I thought it would be best to fix this for clarity of anyone reading it.
Deploy builds both with asserts enabled and asserts disabled to CI.
This also removes uploads to the 'try' bucket, and instead dumps
everything into the two rustc-builds and rustc-builds-alt buckets. This
makes lives easier, as there is only one location for a given "type" of
build, and since we have the git commit hash in the filenames, this is
fine; we won't run into uploads of the same commit.
cc @aidanhs -- this will break crater's logic for downloading `try#xxx` commits since the try bucket won't be uploaded into

impl From<bool> for AtomicBool
This seems like an obvious omission from #45610. ~~I've used the same feature name and version in the hope that this can be backported to beta so it's stabilized with the other impls. If it can't be I'll change it to `1.24.0`.~~
Improve documentation for slice swap/copy/clone operations.
Fixes#45636.
- Demonstrate how to use these operations with slices of differing
lengths
- Demonstrate how to swap/copy/clone sub-slices of a slice using
`split_at_mut`
Stabilize some `ascii_ctype` methods
As discussed in #39658, this PR stabilizes those methods for `u8` and `char`. All inherent `ascii_ctype` for `[u8]` and `str` are removed as we prefer the more explicit version `s.chars().all(|c| c.is_ascii_())`.
This PR doesn't modify the `AsciiExt` trait. There, the `ascii_ctype` methods are still unstable. It is planned to remove those in the future (I think). I had to modify some code in `ascii.rs` to properly implement `AsciiExt` for all types.
Fixes#39658.
Add std::sync::mpsc::Receiver::recv_deadline()
Essentially renames recv_max_until to recv_deadline (mostly copying recv_timeout
documentation). This function is useful to avoid the often unnecessary call to
Instant::now in recv_timeout (e.g. when the user already has a deadline). A
concrete example would be something along those lines:
```rust
use std::sync::mpsc::Receiver;
use std::time::{Duration, Instant};
/// Reads a batch of elements
///
/// Returns as soon as `max_size` elements have been received or `timeout` expires.
fn recv_batch_timeout<T>(receiver: &Receiver<T>, timeout: Duration, max_size: usize) -> Vec<T> {
recv_batch_deadline(receiver, Instant::now() + timeout, max_size)
}
/// Reads a batch of elements
///
/// Returns as soon as `max_size` elements have been received or `deadline` is reached.
fn recv_batch_deadline<T>(receiver: &Receiver<T>, deadline: Instant, max_size: usize) -> Vec<T> {
let mut result = Vec::new();
while let Ok(x) = receiver.recv_deadline(deadline) {
result.push(x);
if result.len() == max_size {
break;
}
}
result
}
```
Disable all macOS dist images to workaround travis-ci/travis-ci#8821
See: travis-ci/travis-ci#8821
Currently the [Travis status](https://www.traviscistatus.com/) is all green, I don't know how long it takes Travis to notice and fix it, so I'm merging this in immediately to keep the queue running today.

I don't believe the previous code `0 ... 2` would run into any real problems, but it seems confusing to read, given that '2' is never a valid binary digit.
As far as I can tell this code is only ever called from within another private method in the trait which has logic to never hand it '2' anyways. I thought we could change this for clarity anyways.
This also removes uploads to the 'try' bucket, and instead dumps
everything into the two rustc-builds and rustc-builds-alt buckets. This
makes lives easier, as there is only one location for a given "type" of
build, and since we have the git commit hash in the filenames, this is

Replace most call to grep in run-make by a script that cat the input.
Introduced a new `src/etc/cat-and-grep.sh` script (called in run-make as `$(CGREP)`), which prints the input and do a grep simultaneously. This is mainly used to debug spurious failures in run-make, such as the spurious error in #45810, as well as real errors such as #46126.
(cc #40713)
Some `grep` still remains, mainly the `grep -c` calls that count the number of matches and print the result to stdout.
Remove `T: Sized` on `ptr::is_null()`
Originally from #44932 -- this is purely a revert of the last commit of that PR, which was removing some changes from the previous commits in the PR. So a revert of a revert means this is code written by @cuviper!
@mikeyhew makes a compelling case in https://github.com/rust-lang/rfcs/issues/433#issuecomment-345495505 for why this is the right way to implement `is_null` for trait objects. And the behavior for slices makes sense to me as well.
```diff
impl<T: ?Sized> *const T {
- pub fn is_null(self) -> bool where T: Sized;
+ pub fn is_null(self) -> bool;
}
impl<T: ?Sized> *mut T {
- pub fn is_null(self) -> bool where T: Sized;
+ pub fn is_null(self) -> bool;
}
ci: Start running wasm32 tests on Travis
This commit allocates a builder to running wasm32 tests on Travis. Not all test
suites pass right now so this is starting out with just the run-pass and the
libcore test suites. This'll hopefully give us a pretty broad set of coverage
for integration in rustc itself as well as a somewhat broad coverage of the llvm
backend itself through integration/unit tests.
