./x.py test should be able to run individual tests
Allows user to be able to run individual tests by specifying filename i.e `./x.py test src/test/run-pass/foo.rs`

Add some groundwork for cross-language LTO.
Implements part of #49879:
- Adds a `-Z cross-lang-lto` flag to rustc
- Makes sure that bitcode is embedded in object files if the flag is set.
This should already allow for using cross language LTO for staticlibs (where one has to invoke the linker manually anyway). However, `rustc` will not try to enable LTO for its own linker invocations yet.

Pass a test directory to rustfmt
Another attempt to fix the rustfmt tests. `RUSTFMT_TEST_DIR` is consumed by Rustfmt in the latext commit (thus the Rustfmt update) because we need a place to create temp files that won't be read-only.

This enables `./x.py test --stage 0 src/libstd --no-doc` and ensures the
stage2-rustc and rustdoc need to be built.

Add "the Rustc book"
This PR introduces a new book into the documentation, "The rustc book". We already have books for Cargo, and for Rustdoc, rustc should have some too. This book is focused on *users* of rustc, and provides a nice place to write documentation for users.
I haven't put content here, but plan on scaffolding it out very soon, and wanted this PR open for a few discussions first. One of those is "what exactly should said TOC be?" I plan on having a proposed one up tomorrow, but figured I'd let people know to start thinking about it now.
The big one is that we also will want to put https://github.com/rust-lang-nursery/rustc-guide in-tree as well, and the naming is... tough. I'm proposing:
* doc.rust-lang.org/rustc is "The Rustc book", to mirror the other tools' books.
* doc.rust-lang.org/rustc-contribution is "The Rustc contribution guide", and contains that book
@nikomatsakis et al, any thoughts on this? I'm not attached to it in particular, but had to put something together to get this discussion going. I think mirroring the other tools is a good idea for this work, but am not sure where exactly that leaves yours.

This ensures that each build will support the testing design of "dry
running" builds. It's also checked that a dry run build is equivalent
step-wise to a "wet" run build; the graphs we generate when running are
directly compared node/node and edge/edge, both for order and contents.
|

In order to run tests, previous commits have cfg'd out various parts of
rustbuild. Generally speaking, these are filesystem-related operations
and process-spawning related parts. Then, rustbuild is run "as normal"
and the various steps that where run are retrieved from the cache and
checked against the expected results.
Note that this means that the current implementation primarily tests
"what" we build, but doesn't actually test that what we build *will*
build. In other words, it doesn't do any form of dependency verification
for any crate. This is possible to implement, but is considered future
work.
This implementation strives to cfg out as little code as possible; it
also does not currently test anywhere near all of rustbuild. The current
tests are also not checked for "correctness," rather, they simply
represent what we do as of this commit, which may be wrong.
Test cases are drawn from the old implementation of rustbuild, though
the expected results may vary.

rustbuild: Tweak where timing information goes
This commit tweaks where timing and step information is printed out as part of
the build, ensuring that we do it as close to the location where work happens as
possible. In rustbuild various functions may perform long blocking work as
dependencies are assembled, so if we print out timing information early on we
may accidentally time more than just the step we were intending to time!

r=Mark-Simulacrum
Use the same RUSTFLAGS for building and testing `bootstrap`
This avoids recompiling the whole dependency graph twice for every `./x.py test` run.

This commit is an implementation of adding custom sections to wasm artifacts in
rustc. The intention here is to expose the ability of the wasm binary format to
contain custom sections with arbitrary user-defined data. Currently neither our
version of LLVM nor LLD supports this so the implementation is currently custom
to rustc itself.
The implementation here is to attach a `#[wasm_custom_section = "foo"]`
attribute to any `const` which has a type like `[u8; N]`. Other types of
constants aren't supported yet but may be added one day! This should hopefully
be enough to get off the ground with *some* custom section support.
The current semantics are that any constant tagged with `#[wasm_custom_section]`
section will be *appended* to the corresponding section in the final output wasm
artifact (and this affects dependencies linked in as well, not just the final
crate). This means that whatever is interpreting the contents must be able to
interpret binary-concatenated sections (or each constant needs to be in its own
custom section).
To test this change the existing `run-make` test suite was moved to a
`run-make-fulldeps` folder and a new `run-make` test suite was added which
applies to all targets by default. This test suite currently only has one test
which only runs for the wasm target (using a node.js script to use `WebAssembly`
in JS to parse the wasm output).

Remove ONLY_BUILD and ONLY_BUILD_TARGETS
Primarily removes `ONLY_BUILD` and `ONLY_BUILD_TARGETS`. These aren't actually needed in the new system since we can simply not take the relevant `host` and `target` fields if we don't want to run with them in `Step::make_run`.
This PR also includes a few other commits which generally clean up the state of rustbuild, but are not related to the `Step` changes.
