Make parse_seq_to_end and parse_path public
(see SergioBenitez/Rocket#660, rust-lang/rust#51265)
Rocket currently uses `parse_seq_to_end` and `parse_path` in its codegen macros. Assuming I tested correctly, this is the minimal set of methods that are currently necessary to build Rocket again. I would be happy to add documentation of this and Rocket's other usages, if desired.

Auto merge of #51519 - ExpHP:issue-51331-b, r=petrochenkov
Fix for $crate var normalization in proc macro for externally defined macros
Fixes #51331, a bug that has existed in at least *some* form for a year and a half.
The PR includes the addition of a `fold_qpath` method to `syntax::fold::Folder`. Overriding this method is useful for folds that modify paths in a way that invalidates indices (insertion or removal of a component), as it provides the opportunity to update `qself.position` in `<A as B>::C` paths. I added it because the bugfix is messy without it.
(unfortunately, grepping around the codebase, I did not see anything else that could use it.)
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.

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)

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.
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.

Rollup merge of #51412 - nnethercote:pending_obligations, r=estebank
Avoid useless Vec clones in pending_obligations().
The only instance of `ObligationForest` in use has an obligation type of
`PendingPredicateObligation`, which contains a `PredicateObligation` and a
`Vec<Ty>`.
`FulfillmentContext::pending_obligations()` calls
`ObligationForest::pending_obligations()`, which clones all the
`PendingPredicateObligation`s. But the `Vec<Ty>` field of those cloned
obligations is never touched.
This patch changes `ObligationForest::pending_obligations()` to
`map_pending_obligations` -- which gives callers control about which part
of the obligation to clone -- and takes advantage of the change to avoid
cloning the `Vec<Ty>`. The change speeds up runs of a few rustc-perf
benchmarks, the best by 1%.
