If you use GYP for your entire project, things should just work.
Otherwise you'll probably have to modify V8's .gyp files. I'm not sure how,
you'll have to find that out for yourself. Try adding -fPIC to the 'cflags'
lists in build/toolchain.gypi.

Compiling/running ia32 binaries on an x86_64 Linux machine should work just
fine. Make sure you have the appropriate toolchain and libraries installed.
Quick test:
$ echo -e '#include stdio.h\nint main() { printf(Hello world\\n); }'

$ g++ -m32 test.cc -o test.bin

For the record, I would recommend not to enable --harmony by default.
There's a reason this flag exists: the features it enables are generally
not ready for prime-time yet. While some might be very close to what will
be enabled by default at some point, others may be crashy, buggy,
incomplete, or
--no-hard-abort

That said, the shared library build seems to be broken on Mac. A workaround
is i18nsupport=off.

Looks like ICU requires something that your Cygwin doesn't have. You can
try to figure out what that is and how to install it in Cygwin, or you can
try building without i18nsupport and see if that works
to build V8, but I haven't
tried that.
Of course, if you want an easy life as a developer, you'll use Linux :-)

But, may I know why the program jumps to ~SealHandleScope()?
Because right after the CALL_GENERATED_CODE there's a block end where a

No, there is no existing way to save and restore V8's state at arbitrary
times. Sven has already explained why it's impossible to implement one.
Assuming that V8 (or a Chrome renderer process) is single-threaded doesn't
help, because it *isn't* single-threaded.
But even if what you're suggesting
