Suggest correct syntax when writing type arg instead of assoc type
- When confusing an associated type with a type argument, suggest the appropriate syntax. Given `Iterator<isize>`, suggest `Iterator<Item = isize>`.
- When encountering multiple missing associated types, emit only one diagnostic.
- Point at associated type def span for context.
- Point at each extra type argument.

rustc_target: separate out an individual alignment quantity type from Align.
Before this PR, `rustc_target::abi::Align` combined "power-of-two alignment quantity" semantics, with a distinction between ABI (required) and preferred alignment (by having two quantities).
After this PR, `Align` is only *one* such quantity, and a new `AbiAndPrefAlign` type is introduced to hold the pair of ABI and preferred `Align` quantities.
`Align` is used everywhere one quantity is necessary/sufficient, simplifying some of the code in codegen/miri, while `AbiAndPrefAlign` only in layout computation (to propagate preferred alignment).

Issue 56128 segment id ice nightly
Tentative fix for #56128
From what I can tell, the problem is that if you have `pub(super) use foo::{a, b}`, then when we explode the `a` and `b`, the segment ids from the `super` path were not getting cloned. However, once I fixed *that*, then I ran into a problem that the "visibility" node-ids were not present in the final HIR -- this is because the visibility of the "stem" that is returned in this case was getting reset to inherited. I don't *think* it is a problem to undo that, so that the visibility is returned unmodified.

Move Cargo.{toml,lock} to the repository root directory.
This should give us back `src/` in errors, panics and debuginfo, for free.

Add SGX target to rustc
This adds the `x86_64-fortanix-unknown-sgx` target specification to the Rust compiler. See #56066 for more details about this target.
Clarifying documentation for collections::hash_map::Entry::or_insert
Previous version does not show that or_insert does not insert the passed value, as the passed value was the same value as what was already in the map.
Return &T / &mut T in ManuallyDrop Deref(Mut) impl
Without this change the generated documentation looks like this:
fn deref(&self) -> &<ManuallyDrop<T> as Deref>::Target
Returning the actual type directly makes the generated docs more clear:
fn deref(&self) -> &T
Basically, compare how the impl for `Box<T>` and `ManuallyDrop<T>` looks in this screenshot:
This is a follow up to 8aa9267 which changed the driver to use lld
directly rather than invoking it through Clang. This change ensures
we pass all the necessary flags to lld.
Doc total order requirement of sort(_unstable)_by
I took the definition of what a total order is from the Ord trait
docs. I specifically put "elements of the slice" because if you
have a slice of f64s, but know none are NaN, then sorting by
partial ord is total in this case. I'm not sure if I should give
such an example in the docs or not.

This test ensures that everything in `env::vars()` is inherited but
that's not actually true because other tests may add env vars after we
spawn the process, causing the test to be flaky! This commit moves the
test to a run-pass test where it can execute in isolation.
Along the way this removes a lot of the platform specificity of the
test, using iteslf to print the environment instead of a foreign process.
The BTreeSet and BTreeMap gdb pretty-printers did not take the node
structure into account, and consequently only worked for shallow sets.
This fixes the problem by iterating over child nodes when needed.
This patch avoids the current approach of implementing some of the
value manipulations in debugger-indepdendent code. This was done for
convenience: a type lookup was needed for the first time, and there
currently are no lldb formatters for these types.
Closes#55771
