We use `is None` instead of `== None` everywhere (which mostly just
means test.py) except in one place in genv8constants.py. Switch to `is
None` in genv8constants.py. This is slightly more efficient, although I
can't imagine that makes a measurable difference here.

Every constant is certainly 4 bytes now, but freebsd's objdump utility
prints out odd byte sequences (5-bytes, 6-bytes and even 9-bytes long)
for v8's data section. We can safely ignore all upper bytes, because all
constants that we're using are just `int`s. Since on all supported
platforms `int` is 32bit long (and anyway v8's constants are 32bit too),
we ignore all higher bits if they were read.
Commit 3d67f89 ("fix generation of v8 constants on freebsd") is an
unfortunate victim of this rollback.

* fixes#2110
* includes V8 postmortem metadata in Solaris builds
* adds GYP support for DTrace probes and ustack helper
* ustack helper derives constants dynamically from libv8_base.a
* build with DTrace support by default on SunOS
