Rework how bootstrap tools are built
This makes bootstrap tools buildable and testable in stage 0 with the downloaded bootstrap compiler, futhermore, it makes it such that they cannot be built in any other stage.
Notably, this will also mean that compiletest may need to wait a cycle before it can use changes to `libtest`, as it no longer depends on the in-tree libtest.
Introduce assembly tests suite
The change introduces a new test suite - **Assembly** tests. The motivation behind this is an ability to perform end-to-end codegen testing with LLVM backend. Turned out, NVPTX backend sometimes missing common Rust features (`i128` and libcalls in the past, and still full atomics support) due to different reasons.
Prior to this change, basic NVPTX assembly tests were implemented within `run-make` suite. Now, it's easier to write additional and maintain existing tests for the target.

cc @eddyb I adjusted mangling scheme expectation, so there is no need to change the tests for #57967
bootstrap: Default to a sensible llvm-suffix.
I used version-channel-sha, hopefully that should work.
I checked that bootstrap builds, but I cannot check anything else since the llvm
build process is started from cargo, and thus calls clang, and thus I hit the
same bug I hope to fix with this change.
Hopefully fixes#59034.

look for python2 symlinks before bootstrap python
Before this commit, if you're running x.py directly on a system where
`python` is symlinked to Python 3, then the `python` config option will
default to a Python 3 interpreter. This causes debuginfo tests to fail
with an opaque error message, since they have a hard requirement on
Python 2.
This commit modifies the Python probe behavior to look for python2.7 and
python2 *before* using the interpreter used to execute `x.py`.

rustc: Update LLVM, remove dead wasm code
This commit updates the LLVM branch to the rebased version of the
upstream release/8.x branch. This includes a wasm patch which means that
the `rewrite_imports` pass in rustc is no longer needed (yay!) and we
can instead rely on `wasm-import-module`, an attribute we're already
emitting, to take care of all the work.
We'll use this as a temporary measure to get an LLVM update landed, but
we'll have to go through and update images later to make sure they've
got the right toolchains.
Rustdoc remove old style files
Reopening of #56577 (which I can't seem to reopen...).
I made the flag unstable so with this change, what was blocking the PR is now gone I assume.
Fixes rustdoc in stage 0, stage 1
When a request for rustdoc is passed for stage 0, x.py build --stage 0
src/tools/rustdoc or ensure(tool::Rustdoc { .. }) with top_stage = 0, we
return the rustdoc for that compiler (i.e., the beta rustdoc).
This fixes stage 0 of https://github.com/rust-lang/rust/issues/52186 as well as being part of general workflow improvements (making stage 0 testing for std work) for rustbuild.
The stage 1 fix (second commit) completely resolves the problem, so this fixes https://github.com/rust-lang/rust/issues/52186.
The RUSTDOC_LIBDIR should be rustc_libdir, not sysroot_libdir; rustdoc
is like the compiler and should link against rustc's libdir.
Some people currently (i.e., in general, may not be on master) have doc
tests working, but no attempt to determine why has been attempted.
