Implement RFC 2421, 'Keyword unreservations (pure, sizeof, alignof, offsetof)
On my local machine I was getting failures in `test/ui-fulldeps`, but I was also getting them again after reverting the change, so I'm hoping that this works.
I removed the test because that's what the other PR that unreserved a keyword did and I feel that it doesn't make sense/keep value to keep a test for something removed years ago.
Miscellaneous changes to rustbuild and CI.
1. Don't build LLVM when running rust-installer.
2. If toolstate is unchanged, don't push a commit to the toolstate repo.
3. Allow `./x.py build src/librustc_codegen_llvm`
4. Added log to track #50887.
This should greatly reduce the commits on the rust-toolstate repository.
`publish_toolstate.py` defaults to keep the old status if a new one is not
found, so nothing needs to be changed to that file.
parser: Split `+=` into `+` and `=` where `+` is explicitly requested (such as generics)
Added functions in tokens to check whether a token leads with `+`. Used them when parsing to allow for token splitting of `+=` into `+` and `=`.

Document size_of for 128-bit integers
We might want to consider separately documenting the alignment of
primitives, rather than just their size, since 128-bit integers, unlike
all other primitives, have an alignment that is not identical to their
size (size_of is 16, align_of is 8)
We used to accumulate a vector of type-check constraints, but now we
generate them as we go, and just store the NLL-style
`OutlivesConstraint` and `TypeTest` information.
Re-enable trivial bounds
cc #50825
Remove implementations from global bounds in winnowing when there is ambiguity.
This results in the reverse of #24066 happening sometimes. I'm not sure if anything can be done about that though.

rustbuild: generate full list of dependencies for metadata
Previously, we didn't send --features to our cargo metadata invocations,
and thus missed some dependencies that we enable through the --features
mechanism.
Do not require stage 2 compiler for rustdoc

I *think* this is correct; though I'm not certain. If it passes CI though I expect that to be good enough...
compiletest: autoremove duplicate .nll.* files (#51204)
UI tests in bless mode should now check to see if `.nll.*` files have a
matching `.*` file. If a match is found, it will be deleted.
This should be extensible to other modes (i.e., Polonius).
On running with `--bless`, the two files removed in #51186 are, in turn,
removed automatically.
