Patch to update the thread local address bad mask during root scanning
while we're anyway walking the thread list (in parallel), instead of
doing a separate single threaded walk over that list.
This patch also removes some platform dependent code, and updates the
thread local bad mask on all platforms, even if it's strictly not needed
on e.g. Solaris/SPARC. However, it doesn't hurt performance wise, and
keeps the model nicely homogeneous across platforms.
