Pass `InferCtxt` to `DropRangeVisitor` so we can resolve vars
The types that we encounter in the `TypeckResults` that we pass to the `DropRangeVisitor` are not yet fully resolved, since that only happens in writeback after type checking is complete.
Instead, pass down the whole `InferCtxt` so that we can resolve any inference vars that have been constrained since they were written into the results. This is similar to how the `MemCategorizationContext` in the `ExprUseVisitor` also needs to pass down both typeck results _and_ the inference context.

Properly handle `Pin<&mut dyn* Trait>` receiver in codegen
This ensures we can actually await a `dyn* Future`, which seems important for async fn in dyn trait.
Also, disable `dyn*` trait upcasting. It's not exactly complete right now, and can cause strange ICEs for no reason -- nobody's using it either. I thought it was cute to implement when I did it, but I didn't think about how it interacts structurally with `CoerceUnsized` correctly.
Fixes#104794, presumably removing `dyn*` upcasting and its `CoerceUnsized` issues does the trick.
Throw error on failure in loading llvm-plugin
The following code silently ignores the error as the `LLVMRustSetLastError` only tracks one error at a time. At all other places where `LLVMRustSetLastError` is used the code immediately returns.

Use `as_deref` in compiler (but only where it makes sense)
This simplifies some code :3
(there are some changes that are not exacly `as_deref`, but more like "clever `Option`/`Result` method use")
Previously if the parent was not in the table, and there was nothing to inherit from, the child's private visibility was used, but that's not correct - the parent may have a larger visibility so we should set it to at least the parent's private visibility.
That parent's private visibility is also inserted into the table for caching, so it's not recalculated later if used again.
By using `display: flex`, we still get the never-wrapping layout with
`#crate-search-div` maxing out and truncating its text. The title itself
winds up always filling its parent, but since `#crate-search` doesn't have
`flex-grow` set, it won't fill available space.
Optimizations removed in the previous commit required this function to behave incorrectly, but now those optimizations are gone so we can fix the bug.

First, they require eagerly calculating private visibility (current normal module), which is somewhat expensive.
Private visibilities are also lost once calculated, instead of being cached in the table.
Second, I cannot prove that the optimizations are correct.
Maybe they can be partially reinstated in the future in cases when it's cheap and provably correct to do them.
They will also probably be merged into `fn update` in that case.

copy doc output files by format
This pr provides copying doc outputs by checking output format without removing output directory on each trigger.
Resolves#103785
Fix hang in where-clause suggestion with `predicate_can_apply`
Using `predicate_may_hold` during error reporting causes an evaluation overflow, which (because we use `evaluate_obligation_no_overflow`) then causes the predicate to need to be re-evaluated locally, which results in a hang.
... but since the "add a where clause" suggestion is best-effort, just throw any overflow errors. No need for 100% accuracy.
r? `@lcnr` who has been thinking about overflows... Let me know if you want more context about this issue, and as always, feel free to reassign.
Fixes#104225
