compiletest: Support opt-in Clang-based run-make tests and use them for testing xLTO.
Some cross-language run-make tests need a Clang compiler that matches the LLVM version of `rustc`. Since such a compiler usually isn't available these tests (marked with the `needs-matching-clang`
directive) are ignored by default.
For some CI jobs we do need these tests to run unconditionally though. In order to support this a `--force-clang-based-tests` flag is added to compiletest. If this flag is specified, `compiletest` will fail if it can't detect an appropriate version of Clang.
@rust-lang/infra The PR doesn't yet enable the tests yet. Do you have any recommendation for which jobs to enable them?

Fix some minor warnings
Since apparently RLS works when initialized in the root repository (🎉) I decided to fix some of the issues it caught.
There are a lot of unused attribute warnings left on `rustc_on_unimplemented` and `rustc_layout_scalar_valid_range_start` but I imagine we can't do much about it due to 2-stage compilation?
Implement optimize(size) and optimize(speed) attributes
This PR implements both `optimize(size)` and `optimize(speed)` attributes.
While the functionality itself works fine now, this PR is not yet complete: the code might be messy in places and, most importantly, the compiletest must be improved with functionality to run tests with custom optimization levels. Otherwise the new attribute cannot be tested properly. Oh, and not all of the RFC is implemented – attribute propagation is not implemented for example.
# TODO
* [x] Improve compiletest so that tests can be written;
* [x] Assign a proper error number (E9999 currently, no idea how to allocate a number properly);
* [ ] Perhaps reduce the duplication in LLVM attribute assignment code…
The new git submodule src/llvm-project is a monorepo replacing src/llvm
and src/tools/{clang,lld,lldb}. This also serves as a rebase for these
projects to the new 8.x branch from trunk.
The src/llvm-emscripten fork is unchanged for now.

Prepare beta 1.33.0
This PR includes the usual changes for a new beta, and suppresses a few lints on libcore: those lints are false positives caused by an internal attribute (`rustc_layout_scalar_valid_range_start`) and only happen on stage0.

Always calculate glob map but only for glob uses
Previously calculating glob map was *opt-in*, however it did record node id -> ident use for every use directive. This aims to see if we can unconditionally calculate the glob map and not regress performance.
Main motivation is to get rid of some of the moving pieces and simplify the compilation interface - this would allow us to entirely remove `CrateAnalysis`. Later, we could easily expose a relevant query, similar to the likes of `maybe_unused_trait_import` (so using precomputed data from the resolver, but which could be rewritten to be on-demand).
r? @nikomatsakis
Local perf run showed mostly noise (except `ctfe-stress-*`) but I'd appreciate if we could do a perf run run here and double-check that this won't regress performance.

Add dist builder for Armv8-M Mainline
This commit adds the Armv8-M Mainline target in the list of targets that
get their dist components built. It also update the build-manifest so
that this target gets also its dist components uploaded.
I took example on other pull requests doing the same thing for another target to make the changes. Please feel free to comment if things needs to be added or removed.
Doing `./x.py dist --target thumbv8m.main-none-eabi` worked locally so I assume that this will also work on the CI.
It will (I think) however need a new release of alexcrichton/cc-rs to include the pull request alexcrichton/cc-rs#363 @alexcrichton
I hope to do the HardFloat version (`thumbv8m.main-none-eabihf`) and Baseline (`thumbv8m.base-none-eabi`) later, as fixes need to be done on compiler-builtins first to support those.
