5a58a4dc6d Rewrite multiple return value handling in SCCP. Before, the -sccp pass 
would turn every getresult instruction into undef.  This helps with

1b706dd680 Fix PR1938 by forcing the code that uses an undefined value to branch one 
way or the other.  Rewriting the code itself prevents subsequent analysis
passes from making contradictory conclusions about the code that could 
cause an infeasible path to be made feasible.

a551c041f9 For PR1319: 
Upgrade to use new Tcl exec based test harness. This exposes 3 bugs that
were previously not being reported:
test/Transforms/GlobalDCE/2002-08-17-FunctionDGE.ll
test/Transforms/GlobalOpt/memset.ll
test/Transforms/IndVarsSimplify/exit_value_tests.llx

9f9fe70b11 Add the SCCP regression tests for APInt expressions. These test cases 
turned up some regressions that have since been fixed. We don't want to
loose the regression tests.

Test cases by Guoling Han.

d029c7e666 Make the llvm-runtest function much more amenable by eliminating all the 
global variables that needed to be passed in. This makes it possible to
add new global variables with only a couple changes (Makefile and llvm-dg.exp)
instead of touching every single dg.exp file.
