Reland "Default `-fsanitize=unreachable`"

This is a reland of commit bcc8b1df414d26c591972e1c4d93025a35bba33e

Reland-specific fixups:

1.  Add a `NO_SANITIZE()` to `base::ImmediateCrash()` to satisfy the
    associated unit test.
2.  The result of `//third_party/abseil-cpp/generate_def_files.py` is
    included in this CL, to fix up swangle builds (c.f. issue 41492832,
    issue 370569882, issue 428045635, issue 482322783, and issue
    526579179)

Original change's description:
> Default `-fsanitize=unreachable`
>
> Control flow has no legitimate reason to reach unreachable points.
> Exclude (release builds of) platforms that set off CQ bots for now;
> we'll revisit them as necessary in the future.
