rollup merge of #21115: dotdash/iter_vec
There are two places left where we used to only know the byte
size of/offset into an array and had to cast to i8 and back to get the
right addresses. But by now, we always know the sizes in terms of the
number of elements in the array. In fact we have to add an extra Mul
instruction so we can use the weird cast-to-u8 code. So we should really
just embrace our new knowledge and use simple GEPs to do the address
calculations.

rollup merge of #21085: pnkfelix/pp-flowgraph-kill-labels
Add `--xpretty flowgraph,unlabelled` variant to the (unstable) flowgraph printing `rustc` option.
This makes the tests much easier to maintain; the particular details of the labels attached to exiting scopes is not worth the effort required to keep it up to date as things change in the compiler internals.

rollup merge of #20463: amaranth/black_box_output
By returning the passed value black_box can be used on data being
passed to a function being benchmarked. This ensures the compiler
does not optimize the function for the input which could result in
the entire function being optimized away.

auto merge of #20290 : jroesch/rust/generalize-impl-bounds, r=nikomatsakis
This should fix both #20020 and #20107. This moves out the code into its own file.
I have a couple concerns that can either be addressed in this PR or in a future one.
- The error reporting for the fulfillment context should be span aware because currently it is attached to the top
of the file which is less then desirable.
- There is a failure in the test file: run-pass/issue-2611-3.rs, this seems like it should be a failure to me, but I am not sure.
As a nit I'm not enthused about the file name, and am open to better suggestions.

Refactor compare_impl_method to use all bounds
Refactor compare_impl_method into its own file. Modify the
code to stop comparing individual parameter bounds.
Instead we now use the predicates list attached to the trait
and implementation generics. This ensures consistency even
when bounds are declared in different places (i.e on
a parameter vs. in a where clause).

Fix Repr output so that it does not ICE when a self-type is
absent. This occurs while printing object type projections for
debugging (note that the `UserString` impl is much more careful about
this).

Prefer GEP instructions over weird pointer casting

Additionally, the pointer calculations in bind_subslice_pat don't handle
zero-sized types correctly, producing slices that point outside the
array that is being matched against. Using GEP fixes that as well.
