When providing the -parseable-output flag to the swift compiler, it will provide json formatted messages about tasks that run.
I added some optional usage information in form of user time, system time and maxrss to the output. This can be used by other tools using the compiler to get some insights about time and memory usage.
Since the output does not longer match processes run (in batch mode), I also added a real_pid field so the client could reason about jobs that belong together if needed.

Swift class metadata has a bit to distinguish it from non-Swift Objective-C
classes. The stable ABI will use a different bit so that stable Swift and
pre-stable Swift can be distinguished from each other.
No bits are actually changed yet. Enabling the new bit needs to wait for
other coordination such as libobjc.

This way they can be used from other projects, like LLDB. The downside
is we now have to make sure the header is included consistently in all
the places we care about, but I think in practice that won't be a problem,
especially not with tests.
