[dataflow]: PATCH: fix regressions on IA64/PPC, add more debug points.

["Seongbae Park" <seongbae dot park at gmail dot com>]

Bootstrapped and regression tested on x86, x86-64, PPC and ia64.
This patch clears up all dataflow branch regressions on above platforms,
except a few extra regressions on x86 (32bit) due to a latent bug
which Ken Zadeck is already working on.
