use gcc::Build rather than deprecated gcc::Config
I did `cargo update -p gcc` to upgrade only this package. Is there further process that should be follwoed when updating a build dependency from crates.io?

Fixes#43973
Update rls
And expose the `CFG_VERSION` env var to tools so they can determine the version of Rust.
This gets the RLS back on master and so completes the PR dance for the generators PR.

Add clippy as a submodule
~~This builds clippy as part of `./x.py build` (locally and in CI).~~
This allows building clippy with `./x.py build src/tools/clippy`
~~Needs https://github.com/nrc/dev-tools-team/issues/18#issuecomment-322456461 to be resolved before it can be merged.~~ Contributers can simply open a PR to clippy and point the submodule at the `pull/$pr_number/head` branch.
This does **not** build clippy or test the clippy test suite at all as per https://github.com/nrc/dev-tools-team/issues/18#issuecomment-321411418

rustbuild: update the rust-src filter for compiler-rt
We wanted `src/compiler-rt/test` filtered from the `rust-src` package,
but that path is now `src/libcompiler_builtins/compiler-rt/test`. This
saves over half of the installed rust-src size. (50MB -> 22MB)

rustbuild: Avoid some extraneous rustc compiles on cross builds
This tweaks a few locations here and there to avoid compiling rustc too many times on our cross-builders on CI.
Closes https://github.com/rust-lang/rust/issues/44132
Fail ./x.py on invalid command
Make the ./x.py script fail when run with an invalid command, like:
```
./x.py nonsense
```
This helps in case of chaining multiple runs, eg.:
```
./x.py biuld && ./x.py test
```
include Cargo.{toml,lock} in rust-src tarball
The lock file is interesting because e.g. xargo could use it to build libstd against the same dependencies that were used for the main build. More generally speaking, just documenting in this form which exact dependencies should be used IMHO makes lots of sense.
I added the Cargo.toml mostly because having the lock without the toml feels odd. Of course, the toml contains references to paths that don't actually exist in the rust-src tarball. Not sure if that is considered a problem.
rustbuild: Rewrite the configure script in Python
This commit rewrites our ancient `./configure` script from shell into Python.
The impetus for this change is to remove `config.mk` which is just a vestige of
the old makefile build system at this point. Instead all configuration is now
solely done through `config.toml`.
The python script allows us to more flexibly program (aka we can use loops
easily) and create a `config.toml` which is based off `config.toml.example`.
This way we can preserve comments and munge various values as we see fit.
It is intended that the configure script here is a drop-in replacement for the
previous configure script, no functional change is intended. Also note that the
rationale for this is also because our build system requires Python, so having a
python script a bit earlier shouldn't cause too many problems.

Discovered in #43767 it turns out the default MSBuild generator in CMake for
whatever reason isn't supporting many of the configuration options we give to
LLVM. To improve the contributor experience automatically enable Ninja if we
find it to ensure that "flavorful" configurations of LLVM work by default in
more situations.
Closes#43767
This controls the value of the crt-static feature used when building the
standard library for a target, as well as the compiler itself when that
target is the host.
They are required for linking it, even though it is a library, because
crtn.o in post_link_objects, as hardcoded in src/librustc_back/target/
linux_musl_base.rs, is added to the linker command line for both
executables and libraries.
Implement a temp redirect for cargo docs
As discussed in
https://github.com/rust-lang/cargo/issues/4040#issuecomment-321639074
This is a redirect meant to be replaced once cargo docs have been
converted to mdbook. We just want *a* URL to ride the trains for now so
that we can print doc.rust-lang.org/cargo in the paper book and
guarantee that it will go *somewhere* useful by the time the book is
printed.
Implemented as a meta redirect in HTML because we don't currently have
any google juice at doc.rust-lang.org/cargo to lose.
When I run `./x.py doc`, this creates a `build/x86_64-apple-darwin/doc/cargo/index.html` file that contains a meta redirect to doc.crates.io. As I understand rust-central-station to work, this should be what we need to make `doc.rust-lang.org/cargo` to work.

Cleanup for "Support compiling rustc without LLVM (try 2)"
This includes a small patch to allow running tests without llvm. Also check if you are not trying to compile a dylib.
