This addresses issue pointed out by niko that prior code would break
if the declaration order for generics does not match how they are fed
into the instantiation of the type itself. (Added some tests
exercising this scenario.)
In particular, as far as I can tell from the error diagnostics, the
former test for E0199 was actually a test for E0198, and there was no
test for E0198.
(I am assuming that one of my previous changes to the `unsafe impl`
checking fixed a latent bug in how these two cases were
differentiated.)
rustbuild: Optimize build times slightly
As the entry point for building the Rust compiler, a good user experience hinges
on this compiling quickly to get to the meat of the problem. To that end use
`#[cfg]`-specific dependencies to avoid building Windows crates on Unix and drop
the `regex` crate for now which was easily replacable with some string
searching.

Leverage Cargo workspaces in rustbuild
This is a continuation of https://github.com/rust-lang/rust/pull/36032 which implements the change to use `cargo metadata` to learn about the crate graph.
Prevent accidentally running 'make install' as sudo.

I missed this in the previous PR, but this seems to work. It should probably go in a rollup, but I don't know how to do those. :/
Avoid some `pat_to_string` calls.
`ty_of_method_or_bare_fn` currently calls `pat_to_string` even when it
doesn't need to. Fixing this avoids hundreds of large allocations (e.g.
171,600 bytes, in `mk_printer`) in several of rustc-benchmarks.
This updates the commit to use workspaces to use `cargo metadata` instead of
hardcoded lists about what to test. This should help us be resilient to updates
in the future on behalf of the crate DAG and minimize the amount of files that
need to be touched.
This involves hacking the code used to run cargo test on various
packages, because it reads Cargo.lock to determine which packages should
be tested. This change implements a blacklist, since that will catch new
crates when they are added in the future.
std: Minor cleanup to libtest
* Don't spawn two threads for all tests, just one now that `catch_unwind` is
stable.
* Remove usage of the unstable `box` keyword
* Remove usage of the unstable `FnBox` trait
rustc: Rename rustc_macro to proc_macro
This commit blanket renames the `rustc_macro` infrastructure to `proc_macro`,
which reflects the general consensus of #35900. A follow up PR to Cargo will be
required to purge the `rustc-macro` name as well.
