Original commit message:

    Fix collection iterator preview with deleted entries

    We used to assume that we know the remaining entries returned by the
    iterator based on the current index. However, that is not accurate,
    since entries skipped by the current index could be deleted.

    In the new approach, we allocate conservatively and shrink the result.

Original commit message:

    [turbofan] Pin pure unreachable values to effect chain (in rep selection)

    Currently, if we lower to a pure computation that is unreachable because
    of some runtime check, we just rename it with DeadValue. This is
    problematic if the pure computation gets later eliminated - that allows
    the DeadValue node float above the check that makes it dead. As we
    conservatively lower DeadValues to debug-break (i.e., crash), we
    might induce crash where we should not.

    With this CL, whenever we lower an impossible effectful node (i.e., with
    Type::None) to a pure node in simplified lowering, we insert an
    Unreachable node there (pinned to the effect chain) and mark the
    impossible node dead (and make it depend on the Unreachable node).

In the initial version of this test there were two zero-length writes to
force tls state to cycle. The second is not necessary, at least not now,
but the first was. The renegotiate() API should ensure that packet
exchange takes place, not its users, so move the zero-length write into
tls.

`readable.resume()` calls `.read(0)`, which in turn previously set
`needReadable = true`, and so a subsequent `.read()` call would
call `_read()` even though enough data was already available.

This can lead to elevated memory usage, because calling `_read()`
when enough data is in the readable buffer means that backpressure
is not being honoured.

Some pty tests persistently hung on the AIX CI buildbots. Fix that by
adding a helper script that properly sets up the pty before spawning
the script under test.

On investigation I discovered that the test runner hung when it tried
to close the slave pty's file descriptor, probably due to a bug in
AIX's pty implementation. I could reproduce it with a short C program.
The test runner also leaked file descriptors to the child process.

I couldn't convince python's `subprocess.Popen()` to do what I wanted
it to do so I opted to move the logic to a helper script that can do
fork/setsid/etc. without having to worry about stomping on state in
tools/test.py.

In the process I also uncovered some bugs in the pty module of the
python distro that ships with macOS 10.14, leading me to reimplement
a sizable chunk of the functionality of that module.

And last but not least, of course there are differences between ptys
on different platforms and the helper script has to paper over that.
Of course.

Really, this commit took me longer to put together than I care to admit.

Caveat emptor: this commit takes the hacky ^D feeding to the slave out
of tools/test.py and puts it in the *.in input files. You can also feed
other control characters to tests, like ^C or ^Z, simply by inserting
them into the corresponding input file. I think that's nice.
