Rollup merge of #56151 - alexcrichton:move-out-flaky-test, r=nagisa 
Move a flaky process test out of libstd

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.

Rollup merge of #56144 - tromey:Bug-55771-btreemap, r=alexcrichton 
Fix BTreeSet and BTreeMap gdb pretty-printers

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

Rollup merge of #56045 - qnighy:additional-sizedness, r=cramertj 
Check arg/ret sizedness at ExprKind::Path

This PR solves three problems:

- #50940: ICE on casting unsized tuple struct constructors
- Unsized tuple struct constructors were callable in presence of `unsized_locals`.
- https://github.com/rust-lang/rust/issues/48055#issuecomment-437178966: we cannot relax `Sized` bounds on stable functions because of fn ptr casting

These are caused by lack of `Sized`ness checks for arguments/retvals at **reference sites of `FnDef` items** (not call sites of the functions). Therefore we can basically add more `Sized` obligations on typeck. However, adding `Sized` obligations arbitrarily breaks type inference; to prevent that I added a new method `require_type_is_sized_deferred` which doesn't interfere usual type inference.
