bde6869ef4 Return Undef if the block has no dominator. This was required to allow 
llvm-gcc build to succeed. Without this change it fails in libstdc++
compilation. This causes no regressions in dejagnu tests. However, 
someone who knows this code better might want to review it.

3e15bf33e0 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

d41ae8bc0c Replace the SSA update code in LCSSA with a bottom-up approach instead of a top 
down approach, inspired by discussions with Tanya.

This approach is significantly faster, because it does not need dominator
frontiers and it does not insert extraneous unused PHI nodes.  For example, on
252.eon, in a release-asserts build, this speeds up LCSSA (which is the slowest
pass in gccas) from 9.14s to 0.74s on my G5.  This code is also slightly smaller
and significantly simpler than the old code.

Amusingly, in a normal Release build (which includes the
"assert(L->isLCSSAForm());" assertion), asserting that the result of LCSSA
is in LCSSA form is actually slower than the LCSSA transformation pass
itself on 252.eon.  I will see if Loop::isLCSSAForm can be sped up next.

e4e1ecd37c Add a fix for an issue where LCSSA would fail to insert undef's in some corner 
cases.  Ideally, this issue will go away in the future as LCSSA gets smarter
about which Phi nodes it inserts.

13a68e4257 Use the PotDoms map to memoize 'dominating value' lookup. With this patch, 
LCSSA is still the slowest pass when gccas'ing 252.eon, but now it only takes
39s instead of 289s. :)

7be3f1e078 Fix a bug that was causing major slowdowns in povray. This was due to LCSSA 
not handling PHI nodes correctly when determining if a value was live-out.

from 6565 to 485.

3d2aa47bd3 Fix for 2006-06-26-MultipleExitsSingleBlock. 
If a single exit block has multiple predecessors within the loop, it will
appear in the exit blocks list more than once.  LCSSA needs to take that into
account so that it doesn't double process that exit block.
