6932399f9b Bug fix: In preventing static global variables from being printed twice, 
I also prevented external globals from being printed twice, but they
should (extern declaration and definition).

a923b0f49f Handle post dominance correctly in the case where blocks do not have a path to 
the exit node.

85ba0832e5 Fix a nasty problem with dominance calculation for unreachable blocks. 
If we had a CFG that look like Entry -> B, Unreachable -> B, then we would
not correctly determine that Entry dominated B, because Entry did not
apparently dominate "unreachable".  This patch fixes this by making the entry
node dominate all blocks, including unreachable ones.

267eb7dc67 The wall clock timer (implementing using the RTC or cycle counter on x86) is 
so much more accurate than the per process timers that we get better results
(less noise) by sorting according to wall time than process time.
