9852b23657 Rollup merge of #47600 - varkor:empty-never-array, r=eddyb
Fix type inhabitedness check for arrays

Arrays of uninhabited types were considered to also be uninhabited if
their length had not been evaluated, causing unsoundness.

Fixes #47563.

304885d959 Rollup merge of #47460 - Mark-Simulacrum:bootstrap-check, r=alexcrichton
Add ./x.py check src/{libstd,libtest,librustc}

This currently only supports a limited subset of the full compilation,
but is likely 90% of what people will want and is possible without
building a full compiler (and also building LLVM). In theory, this means
that contributors who don't want to build LLVM now have an easy way to
compile locally, though running tests won't work.

1bdef2f8fc Rollup merge of #47453 - pftbest:nointas, r=alexcrichton
Fix no_integrated_as option to work with new codegen architecture.

Old implementation called the assembler once per crate, but we need to call
it for each object file instead, because a single crate can now have more
than one object file.

This patch fixes issue #45836 (Can't compile core for msp430 in release mode)

This change can be tested on x86_64 using
```sh
export RUSTFLAGS="-C no_integrated_as -C save_temps"
```

rustc_trans: ignore trailing padding larger than 8 bytes.

Fixes #45662 by ignoring a missing second register component, as it could be entirely padding.

3b2403306f Rollup merge of #47415 - varkor:cgu-partition-heuristic, r=michaelwoerister
Add CGU size heuristic for partitioning

This addresses the concern of #47316 by estimating CGU size based on
the size of its MIR. Looking at the size estimate differences for a
small selection of crates, this heuristic produces different orderings,
which should more accurately reflect optimisation time. (Fixes #47316.)

a809da3fee Rollup merge of #47702 - etaoins:fix-into-cast-paren-precedence, r=petrochenkov
Fix into() cast paren check precedence

As discussed in #47699 the logic for determining if an expression needs parenthesis when suggesting an `.into()` cast is incorrect. Two broken examples from nightly are:

```
error[E0308]: mismatched types
 --> main.rs:4:10
  |
4 |     test(foo as i8);
  |          ^^^^^^^^^ expected i32, found i8
help: you can cast an `i8` to `i32`, which will sign-extend the source value
  |
4 |     test(foo as i8.into());
  |
```

```
error[E0308]: mismatched types
 --> main.rs:4:10
  |
4 |     test(*foo);
  |          ^^^^ expected i32, found i8
help: you can cast an `i8` to `i32`, which will sign-extend the source value
  |
4 |     test(*foo.into());
  |
```

As suggested by @petrochenkov switch the precedence check to `PREC_POSTFIX`. This catches both `as` and unary operators. Fixes #47699.

bbdc5b9637 Rollup merge of #47679 - etaoins:remove-redundant-backtrace-hint, r=estebank
Remove broken redundant backtrace hint

When the compiler driver panics it attempts to show a hint about using `RUST_BACKTRACE`. However, the logic is currently reversed to the hint is only shown if `RUST_BACKTRACE` is **already**   set:

```shell
> RUST_BACKTRACE=1 rustc /dev/null --crate-type proc-macro
error: internal compiler error: unexpected panic
...
note: run with `RUST_BACKTRACE=1` for a backtrace

thread 'rustc' panicked at 'attempt to subtract with overflow', librustc_errors/emitter.rs:287:49
note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.

> RUST_BACKTRACE=0 rustc /dev/null --crate-type proc-macro
error: internal compiler error: unexpected panic
...
thread 'rustc' panicked at 'attempt to subtract with overflow', librustc_errors/emitter.rs:287:49
note: Run with `RUST_BACKTRACE=1` for a backtrace.
```

As the `panic` itself already has a working `RUST_BACKTRACE` hint just remove the broken duplicate hint entirely.

e26aac5a9f Rollup merge of #47534 - estebank:suggest-public-traits, r=petrochenkov
On missing method do not suggest private traits

When encountering a method call for an ADT that doesn't have any
implementation of it, we search for traits that could be implemented
that do have that method. Filter out private non-local traits that would
not be able to be implemented.

This doesn't account for public traits that are in a private scope, but
works as a first approximation and is a more correct behavior than the
current one.

Fix #45781.

63b3168448 llvm6: Don't clone LLVM modules on wasm
The comment for why cloning exists doesn't actually apply for wasm today and
apparently cloning is causing subtle bugs in LLVM, so let's just avoid it
altogether. More specifically after we emit the assembly for the wasm target we
don't actually use the module again, so there's no need to keep both around.

This seemed to be causing some scary verifier assertions in LLVM which seemed to
be uncovered by presumably (?) buggy behavior. Let's just avoid it for now and
make the wasm target slightly more lean in the process.

It looks like LLVM also removed it in llvm-mirror/llvm@f45adc29d in favor of the
name "GNU64". This was added in the thought that we'd need such a variant when
adding mips64 support but we ended up not needing it! For now let's just
removing the various support on the Rust side of things.

9eeecd2ada llvm6: Tweak fast math intrinsics
Looks like they did some refactoring of flags in the backend and this should

function which should hopefully have the same behavior as before.
