Correct the recursive PHI node handling routines in a way that CANNOT induce
infinite loops (using the new replaceSymbolicValuesWithConcrete method).

This patch reverts this patch:
http://mail.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20050131/023830.html

... which was an attempted fix for this problem.  Unfortunately, that patch
caused test/Regression/Transforms/IndVarsSimplify/exit_value_tests.llx to fail
and slightly castrated the entire analysis.  This patch fixes it right.

This patch is dedicated to jeffc, for making me deal with this.  :)

In the case where there are other call sites to the same set of functions, this
permits us to just inline the temporary graph instead of all of the callees.
