This fixes a mistake where miri was accidentally left out of the
build-manifest parsing, meaning that today's nightly generated a
manifest with invalid urls!
On Windows process exit codes are never signals but rather always 32-bit
integers. Most faults like segfaults and such end up having large
integers used to represent them, like STATUS_ACCESS_VIOLATION being
0xC0000005. Currently, however, when an `ExitStatus` is printed this
ends up getting rendered as 3221225477 which is somewhat more difficult
to debug.
This commit adds a branch in `Display for ExitStatus` on Windows which
handles exit statuses where the high bit is set and prints those exit
statuses as hex instead of with decimals. This will hopefully preserve
the current display for small exit statuses (like `exit code: 22`), but
assist in quickly debugging segfaults/access violations/etc. I've
found at least that the hex codes are easier to search for than decimal.
I wasn't able to find any official documentation saying that all system
exit codes have the high bit set, but I figure it's a good enough
heuristic for now.
This fixes#57462.
The relevant part from the hir type collector is:
```
DEBUG 2019-01-09T15:42:58Z: rustc::hir::map::collector: hir_map: NodeId(32) => Entry { parent: NodeId(33), dep_node: 4294967040, node: Expr(expr(32: <Foo>::new)) }

DEBUG 2019-01-09T15:42:58Z: rustc::hir::map::collector: hir_map: NodeId(31) => Entry { parent: NodeId(32), dep_node: 4294967040, node: PathSegment(PathSegment { ident: new#0, id: Some(NodeId(31)), def: Some(Err), args: None, infer_types: true }) }
```
We have the right ID when looking for NodeId(31) and try with NodeId(32) (which
is the right thing to look for) from get_path_data, but not for the segments
that we write from `write_sub_paths_truncated`.
Basically `process_path` takes an id which is always the parent, and that we
fall back to in `get_path_data()`, so we get the right result for the last path
segment, but not for the other segments that get written to from
`write_sub_paths_truncated`.
I think we can stop passing the explicit id around to `get_path_data` now, will
consider sending that as a followup.
The version included in Ubuntu 16.04 repositories in the dist-various-1
docker, Arm GCC version 4.9, does not support the new Armv8-M
architecture.
This commit adds the team-gcc-arm-embedded PPA to get through APT a
newer version of Arm GCC.
This commit adds the Armv8-M Mainline target in the list of targets that
get their dist components built. It also update the build-manifest so
that this target gets also its dist components uploaded.
Reborrow Pin<P> using &mut in `Pin::set`
Fixes https://github.com/rust-lang/rust/issues/57339.
This makes it possible to call `.set` multiple times without
using `.as_mut()` first to reborrow the pointer.

Currently, there are many places in rustc, where we use
with_freevars to iterate over freevars of a closure. The
problem with this is the argument to with_freevars is a
NodeId and this will get in the way of our eventual goal
of solving for issue (#53488), sub-issue (#56905)
Adding a map to TypeckTables to get the list of all the Upvars
given a closureID. This is help us get rid of the recurring
pattern in the codebase of iterating over the free vars
using with_freevars.
