std: Bump time margin in std::time tests
I believe that because Windows' unit of resolution is 100ns that this unit of
time will ensure that the assertions will hold true as it's representable in the
native format.

[breaking-change], needs crater run (cc @brson or @alexcrichton )
The pattern with parens `UnitVariant(..)` for unit variants seems to be popular in rustc (see the second commit), but mostly used by one person (@nikomatsakis), according to git blame. If it causes breakage on crates.io I'll add an exceptional case for it.

Auto merge of #30064 - fhartwig:macro-suggestions, r=sanxiyn
Fixes #13677
This does the same sort of suggestion for misspelt macros that we already do for misspelt identifiers.
Example. Compiling this program:
```rust
macro_rules! foo {
($e:expr) => ( $e )
}
fn main() {
fob!("hello!");
}
```
gives the following error message:
```
/Users/mcp/temp/test.rs:7:5: 7:8 error: macro undefined: 'fob!'
/Users/mcp/temp/test.rs:7 fob!("hello!");
^~~
/Users/mcp/temp/test.rs:7:5: 7:8 help: did you mean `foo`?
/Users/mcp/temp/test.rs:7 fob!("hello!");
```
I had to move the levenshtein distance function into libsyntax for this. Maybe this should live somewhere else (some utility crate?), but I couldn't find a crate to put it in that is imported by libsyntax and the other rustc crates.

under OpenBSD and Bitrig, it is an error to pass an empty argv
argument to execve(2). It results the test fail as execve(2) don't exec
and set errno to EINVAL.
instead, make argv with two arguments (in order to differenciate the
initial call, from the execve call).

Auto merge of #30043 - arielb1:split-metadata, r=nikomatsakis
This improves bootstrap times because of better parallelism - though I need to measure how much - and allows metadata to be modified without triggering a full recompile. This also ensures that metadata handling and the rest of rustc remain decoupled, which is a first step for switching to a new metadata format.
This is a [breaking-change] to all plugin authors because of the following renames:
* `rustc::plugin` is now `rustc_plugin`
* `rustc::metadata` is now `rustc_metadata`
* Most data types from `rustc::metadata`, along with `LOCAL_CRATE`, are now in `rustc::middle::cstore`.
* The CStore methods were split between the `rustc::middle::CrateStore` trait (and trait object) and the `rustc_metadata::cstore::CStore`, with an `Rc<CrateStore>` stored in the `Session`. The inner `CStore` can be accessed via the inner `Any` bound, but this is deprecated.

The graph extent mechanism is not good. I have some ideas for a better replacement, but this PR simply removes it. It also stops recursing on statement scopes and processes them using an "on the heap" stack, which fixes #29466.

Typical algebra currently doesn't work on the types in std::time currently (see
[this comment][comment]), so tweak the tests to account for this property.

Remove the GraphExtents, the design of which seems bogus. They carried
the right information, but it's hard to maintain in the face of
optimizations, and in the form that the analyses probably actually want.
