ef96037f7e Rollup merge of #31177 - alexcrichton:no-stdio, r=sfackler
On all platforms, reading from stdin where the actual stdin isn't present should
return 0 bytes as having been read rather than the entire buffer.

On Windows, handle the case where we're inheriting stdio handles but one of them
isn't present. Currently the behavior is to fail returning an I/O error but
instead this commit corrects it to detecting this situation and propagating the
non-set handle.

Closes #31167

The previous example did not do what its description said. In it panicked on integer overflow in debug mode, and went into an infinite loop in release mode (wrapping back to 0 after printing 254).

43c1a173a8 Auto merge of #31105 - jseyfried:fix_lexical_scoping, r=nrc
This fixes #23880, a scoping bug in which items in a block are shadowed by local variables and type parameters that are in scope.

After this PR, an item in a block will shadow any local variables or type parameters above the item in the scope hierarchy. Items in a block will continue to be shadowed by local variables in the same block (even if the item is defined after the local variable).

This is a [breaking-change]. For example, the following code breaks:
```rust
fn foo() {
    let mut f = 1;
    {
        fn f() {}
        f += 1; // This will resolve to the function instead of the local variable
    }
}

0b511e82ab Initial work towards abort-free compilation
The goal is that the compiler will pass `Result`s around rather than using abort_if_errors. To preserve behaviour we currently abort at the top level. I've removed all other aborts from the driver, but haven't touched any of the nested aborts.

faf0852fc1 Resolve: fix #23880, a scoping bug
This fixes a bug in which items in a block are shadowed by local variables and type parameters that are in scope.
It is a [breaking-change]. For example, the following code breaks:

```rust
fn foo() {
    let mut f = 1;
    {
        fn f() {}
        f += 1; // This will now resolve to the function instead of the local variable
    }
}
```

Any breakage can be fixed by renaming the item that is no longer shadowed.

faf6d1e873 Auto merge of #31065 - nrc:ident-correct, r=pnkfelix
This PR adds some minor error correction to the parser - if there is a missing ident, we recover and carry on. It also makes compilation more robust so that non-fatal errors (which is still most of them, unfortunately) in parsing do not cause us to abort compilation. The effect is that a program with a missing or incorrect ident can get all the way to type checking.

dc6ed63655 Added info on the build system to contributing guide
I recently wrote a blog post on contributing to the Rust compiler which
gained some interest. It was mentioned in a comment on Reddit that it
would be useful to integrate some of the information from that post to
the official contributing guide.

This is the start of my efforts to integrate what I wrote with the
official guide.

This commit adds information on the build system. It is not a complete
guide on the build system, but it should be enough to provide a good
starting place for those wishing to contribute.

c22cb5359f Auto merge of #31176 - frewsxcv:incorrect-pass-kind, r=dotdash
Register LLVM passes with the correct LLVM pass manager.

LLVM was upgraded to a new version in this commit:

f9d4149c29

which was part of this pull request:

https://github.com/rust-lang/rust/issues/26025

Consider the following two lines from that commit:

f9d4149c29 (diff-a3b24dbe2ea7c1981f9ac79f9745f40aL462)

f9d4149c29 (diff-a3b24dbe2ea7c1981f9ac79f9745f40aL469)

The purpose of these lines is to register LLVM passes. Prior to the that
commit, the passes being handled were assumed to be ModulePasses (a
specific type of LLVM pass) since they were being added to a ModulePass
manager. After that commit, both lines were refactored (presumably in an
attempt to DRY out the code), but the ModulePasses were changed to be
registered to a FunctionPass manager. This change resulted in
ModulePasses being run, but a Function object was being passed as a
parameter to the pass instead of a Module, which resulted in
segmentation faults.

In this commit, I changed relevant sections of the code to check the
type of the passes being added and register them to the appropriate pass
manager.
