77aa419991 Provide a function that ensures MBB numbering is dense and inorder. This 
can be used by MachineFunctionPasses who need this property.

f5ad6f5e2e Simplify logic further. 
Ensure that we copy KnownProperties before calling visitBasicBlock, else
we may leak properties into blocks where they don't belong.

9b15198af4 Fix for PR929. The PHI nodes were being gone through for each instruction 
in a successor block for every block...resulting in some O(N^k) algorithm
which wasn't very good for performance. Calculating this information up
front and keeping it in a map made it much faster.

bfbe137f4c Fix PR932 and Analysis/Dominators/2006-10-02-BreakCritEdges.ll: 
The critical edge block dominates the dest block if the destblock dominates
all edges other than the one incoming from the critical edge.

f0c3081939 Teach globalsmodref-aa to track scalar pointer global variables which point 
to unaliased allocations.  Use this information to disambiguate pointers loaded
from them.  This is a very common case, so it's worthwhile to handle efficiently.

This implements Analysis/GlobalsModRef/indirect-global.ll
