Should hopefully bring in a few more `cargo fix`-related fixes.

Omit the vendor component in Fuchsia triple
Previously, using unknown as the vendor value would lead to the same
result, but with the multiarch runtimes support in Clang, the target is
now used to locate the runtime libraries and so the format is important.
The denormalized format with omitted vendor component is the format we
use with Clang and should be using for Rust as well.

Rollup of bare_trait_objects PRs
All deny attributes were moved into bootstrap so they can be disabled with a line of config.
Warnings for external tools are allowed and it's up to the tool's maintainer to keep it warnings free.

rustdoc: set panic output before starting compiler thread pool
When the compiler was updated to run on a thread pool, rustdoc's processing of compiler/doctest stderr/stdout was moved into each compiler thread. However, this caused output of the test to be lost if the test failed at *runtime* instead of compile time. This change sets up the `set_panic` call and output bomb before starting the compiler thread pool, so that the `Drop` call that writes back to the test's stdout happens after the test runs, not just after it compiles.
Fixes https://github.com/rust-lang/rust/issues/51162

overhaul exit codes for rustc and rustdoc
This commit changes the exit status of rustc to 1 in the presence of
compilation errors. In the event of an unexpected panic (ICE) the
standard panic error exit status of 101 remains.
A run-make test is added to ensure that the exit code does not regress,
and compiletest is updated to check for an exit status of 1 or 101,
depending on the mode and suite.
This is a breaking change for custom drivers.
Note that while changes were made to the rustdoc binary, there is no
intended behavior change. rustdoc errors (i.e., failed lints) will still
report 101. While this could *also* hide potential ICEs, I will leave
that work to a future PR.
Fixes #51971.

Preliminary work for incremental ThinLTO.
Since implementing incremental ThinLTO is a bit more involved than I initially thought, I'm splitting out some of the things that already work. This PR (1) adds a way accessing some ThinLTO information in `rustc` and (2) does some cleanup around CGU/object file naming (which makes things quite a bit nicer).
This is probably best reviewed one commit at a time.

make pretty source comparison check be fatal (fixes #52255)
This is not ready for merging because it reveals (at least) two regressions in the pretty suite. Should I attempt to fix those in this PR also?

This commit upgrades the main LLVM submodule to LLVM's current master branch.
The LLD submodule is updated in tandem as well as compiler-builtins.
Along the way support was also added for LLVM 7's new features. This primarily
includes the support for custom section concatenation natively in LLD so we now
add wasm custom sections in LLVM IR rather than having custom support in rustc
itself for doing so.
Some other miscellaneous changes are:
* We now pass `--gc-sections` to `wasm-ld`
* The optimization level is now passed to `wasm-ld`
* A `--stack-first` option is passed to LLD to have stack overflow always cause
a trap instead of corrupting static data
* The wasm target for LLVM switched to `wasm32-unknown-unknown`.
* The syntax for aligned pointers has changed in LLVM IR and tests are updated
to reflect this.
* The `thumbv6m-none-eabi` target is disabled due to an [LLVM bug][llbug]
Nowadays we've been mostly only upgrading whenever there's a major release of
LLVM but enough changes have been happening on the wasm target that there's been
growing motivation for quite some time now to upgrade out version of LLD. To
upgrade LLD, however, we need to upgrade LLVM to avoid needing to build yet
another version of LLVM on the builders.
The revision of LLVM in use here is arbitrarily chosen. We will likely need to
continue to update it over time if and when we discover bugs. Once LLVM 7 is
fully released we can switch to that channel as well.

Mostly fix metadata_only backend and extract some code out of rustc_codegen_llvm
Removes dependency on the `ar` crate and removes the `llvm.enabled` config option in favour of setting `rust.codegen-backends` to `[]`.
