This also adds assertions that the operations work as expected.

Since switching CI to Azure Pipelines it seems that this test seems
to fail more consistently, so let's disable that for now. It helps
that we have less than a week before release - we disallow PRs that
break the tools to land in this period, so this makes landing critical
PRs smoother  now.

MSVC link output improve

Resolves rust-lang#35785.

However i haven't come up with a idea to add test case for this :(

Adjust warning of -C extra-filename with -o.

If `--emit` includes multiple unnamed outputs, and `-o` was specified, and `-C extra-filename` was specified, the compiler would warn that `-C extra-filename` was ignored, but this is not true.  The "adapting" of the filenames includes the extra-filename info.

Since this is a little convoluted and hard to follow, here is a little chart to summarize when running with `rustc foo.rs -o xyz -C extra-filename=asdf`

`--emit` | Result
---------|--------
`link` | `xyz` (extra-filename ignored)
`link,dep-info` | `xyzasdf`, `xyzasdf.d` (this PR removes the incorrect warning)

As to whether or not this behavior is the best choice is another question.

Switch tracking issue for `#![feature(slice_patterns)]`

Switches the tracking issue for `#![feature(slice_patterns)]` to a fresh one in rust-lang#62254 due to new RFCs.

Closes rust-lang#23121.

syntax: Unsupport `foo! bar { ... }` macros in the parser

Their support in expansion was removed in rust-lang#61606.

Also un-reserve `macro_rules` as a macro name, there's no ambiguity between `macro_rules` definitions and macro calls (it also wasn't reserved correctly).
