JSC_enableProfiler=true should also cause JSGlobalData to save the profiler output somewhere

Added the ability to save profiler output with JSC_enableProfiler=true. It will save it
to the current directory, or JSC_PROFILER_PATH if the latter was specified.
This works by saving the Profiler::Database either when it is destroyed or atexit(),
whichever happens first.
This allows use of the profiler from any WebKit client.

I got tired of the fact that getpid(2) is not a syscall on Windows (unless you do
_getpid() I believe), so I wrote a header that abstracts it. I also changed existing
code that uses getpid() to use WTF::getCurrentProcessID().
