    • Remove `absl::weak_equality` and `absl::strong_equality`. · a39d71a8 
      The corresponding `std` types were removed before C++20 was finalized:
https://wg21.link/P1959R0.

They are unused. The language mechanisms and recommendations changed since they
were originally proposed. In particular:

* An explicitly defaulted `operator==` is defined in terms of memberwise
  `operator==` rather than sibling `operator<=>`.

* An `operator!=` can be implicitly added to an overload set in terms of
  `operator==` rather than `operator<=>`.

* A class which has equality but not ordering defined should provide
  `operator==` rather than `operator<=>`.

    • Speed-up absl::Symbolize by ~6x via faster file reads. · aa146013 
      absl::Symbolize does tons of tiny reads. Speed this up by switching
from lseek+read to a pread, and by reading more data than requested
into a buffer.

A faster absl::Symbolize will be helpful in tests and when printing
stack traces on /threadz etc.

Results for absl::Symbolize benchmark that exercises uncached behavior
of absl::Symbolize:

```
name          old time/op  new time/op  delta
BM_Symbolize  16.4ms ±12%   2.6ms ± 0%  -84.06%  (p=0.001 n=5+9)
```

    • Properly handle signal stacks and frame-size calculations · bb7bbb12 
      We can determine the signal stack, so use that information to
make better decisions about when to calculate the frame size
and when not to. This fixes a several tests where the memory
layout had the signal stack and main stack in position that
confused some of the greater-than/less-than comparisons.

Also cleanup certain types to avoid more casting than necessary.

    • Add control()/slot() functions to iterator/const_iterator. · 116ee0fe 
      This allows for avoiding e.g. it.inner_.slot_ on const iterators.

Also, refactor HashtableDebugAccess::AllocatedByteSize to use regular iteration instead of looking directly at control/slot_array of the table in order to support small object optimization.
