[libc++][spaceship] Implement `lexicographical_compare_three_way`

The implementation makes use of the freedom added by LWG 3410. We have
two variants of this algorithm:
* a fast path for random access iterators: This fast path computes the
  maximum number of loop iterations up-front and does not compare the
  iterators against their limits on every loop iteration.
* A basic implementation for all other iterators: This implementation
  compares the iterators against their limits in every loop iteration.
  However, it still takes advantage of the freedom added by LWG 3410 to
  avoid unnecessary additional iterator comparisons, as originally
  specified by P1614R2.

https://godbolt.org/z/7xbMEen5e shows the benefit of the fast path:
The hot loop generated of `lexicographical_compare_three_way3` is
more tight than for `lexicographical_compare_three_way1`. The added
benchmark illustrates how this leads to a 30% - 50% performance
improvement on integer vectors.

Implements part of P1614R2 "The Mothership has Landed"

Fixes LWG 3410 and LWG 3350

[lldb] Add the ability to provide a message to a progress event update

Consider the following example as motivation. Say you have to load
symbols for 3 dynamic libraries: `libFoo`, `libBar` and `libBaz`.
Currently, there are two ways to report process for this operation:

 1. As 3 separate progress instances. In this case you create a progress
    instance with the message "Loading symbols: libFoo", "Loading
    symbols: libBar", and "Loading symbols: libBaz" respectively. Each
    progress event gets a unique ID and therefore cannot be correlated
    by the consumer.

 2. As 1 progress instance with 3 units of work. The title would be
    "Loading symbols" and you call Progress::Increment for each of the
    libraries. The 3 progress events share the same ID and can easily be
    correlated, however, in the current design, there's no way to
    include the name of the libraries.

The second approach is preferred when the amount of work is known in
advance, because determinate progress can be reported (i.e. x out of y
operations completed). An additional benefit is that the progress
consumer can decide to ignore certain progress updates by their ID if
they are deemed to noisy, which isn't trivial for the first approach due
to the use of different progress IDs.

This patch adds the ability to add a message (detail) to a progress
event update. For the example described above, progress can now be
displayed as shown:

  [1/3] Loading symbols: libFoo
  [2/3] Loading symbols: libBar
  [3/3] Loading symbols: libBaz
