Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

No! Really! Serious this time...It was how the vreg uses were being
adjusted that was causing hte Olden tests to fail. I corrected this and
the Olden and Regression tests all passed.

instructions once). We create a map out of them. Then it's no problem to
use the information in it during elimination...

terminators to use virtual registers, and update phi elimination to correctly
update livevar when eliminating phi's.  This fixes a problem on a testcase

than before.  Because this is the case, we can compute the first non-phi
instruction once when de-phi'ing a block.  This shaves ~4s off of
phielimination of _Z7yyparsev in kimwitu++ from 109s -> 105s.  There are
still much more important gains to come.
