ICU's UChar was uint16_t (non-Win) or wchar_t (Windows). It's switching
to char16_t in both C/C++ API. It needs some changes. Fortunately,
v8 needs only a couple of changes because v8 has been using
reinterpret_cast in many places calling ICU API.

This change was confirmed to work fine with ICU-59-to-be.

Chrome no longer calls v8::Isolate::Dispose on shutdown, essentially preventing
the use of V8 stats within chrome/content_shell. This CL adds a basic hook to
the api that is then used to only print the stats.

We need to check whether advancing the iterator moved us beyong the end
of the bitmap. This has not been flushed out as our inlined bitmap is
still in valid memory.

In practice this is not a problem because the value is never used as we
are at the end of the bitmap. Asan rightfully complains when using an
external bitmap though.

The BitcastWordToTagged operator is used for bump pointer allocation to
construct the actual HeapObject pointer. The input to this operator is
a naked pointer (derived from the allocation top). If this input value
is live across an allocation, then the resulting tagged pointer is
invalid because the GC might have scavenged new space in the meantime.

That means we must not allow Node splitting (in the Scheduler) for these
instructions, as that could extend the live range of the naked pointer
input across arbitrary code. As such, this operator must not be marked
as pure.
