CallICs have had some confused tracing, because the IC state is not
entirely captured by the installed code stub - it lives in the type
vector.

Change tracing to be able to use the vector state changes instead.
Introduced a DEFAULT state to be used by all vector-based ICs.

CallIC, as the first of vector-based ICs didn't update the ic with type
count counter and the generic count counter correctly. This CL fixes
that.

The CallIC Array custom IC stub read from the type vector, expecting
to get an AllocationSite. But there are paths in the system where a
type vector can be re-created with default values, even though we
currently grant an exception to clearing of vector slots with
AllocationSites in them at gc time.

This is a mostly mechanical CL (more than 90% Emacs macros and
query-replace-regexp) moving FILE*/StringStream*-based APIs to
OStream-based APIs. There are a few places where this had to stop,
otherwise the CL would be even bigger, but this can easily and
incrementally cleaned up later.
