Linkname should have uses at both ends,
and then no fake assembly file is needed.

16d3040a84 maps: fix aliasing problems with Clone
Make sure to alloc+copy large keys and values instead of aliasing them,
when they might be updated by a future assignment.

Fixes #64474

598958f0f2 maps: remove Keys and Values
Preserve the names in case we want them to return an iterator.
Keep the efficient runtime implementations for now,
as we will probably want them under some name, perhaps KeysSlice
and ValuesSlice.

Fixes #61538

411c99671a slices, maps: add examples; doc comment fixes
There are currently no examples in the new slices and maps package, so
add some. This adds examples for most functions in the slices package
except the very obvious ones, and adds examples for the DeleteFunc and
EqualFunc functions in the maps package.

Also clarify/correct a few doc comments:

* EqualFunc takes an "equality" function, not a "comparison" function
* It's confusing for Delete and DeleteFunc to say they "do not create a
  new slice", as they do return a new slice. They already say they
  "return the modified slice" which is enough.
* Similar for Compact, and mention that it returns the modified slice
  (and say why)
* Note that CompactFunc keeps the first element in equal runs
* Say what cmp is in SortStableFunc and IsSortedFunc
* Say that MinFunc and MaxFunc return the first value
