Chris Lattner c0968c72ff new testcase for a simple optimization that simplifycfg is about to do. 
All CFG edges to DEAD should be eliminated.

Chris Lattner 272f3527a3 add another testcase to make sure it gets turned into a switch (answer: yes it does)

Chris Lattner 21adf7d36e Add new test to make sure simplifycfg doesn't leave around trivially 
dead instructions.

Chris Lattner 6299141c4e When converting phi nodes into select instructions, we shouldn't promote PHI 
nodes unless we KNOW that we are able to promote all of them.  In this case
promoting the phi to a select is silly because we will always have to do the
call conditionally.  As such, select promotion is actually a pessimization.

Chris Lattner eee347209f Fix testcase. For some reason this was failing only with a release build and 
not with a debug build?  Rather testrunner only caught it in that case.

Chris Lattner 52a71340c1 Fix a test that was "broken" by new optimizations. The transformation we 
are doing is certainly correct, its just that we didn't have the capability
to do it when the testcase was written (no select instr)

John Criswell d064f2124e Modify test to use the %t substition (temporary name). This is available 
in the QMTest Testrunner tests.
Please note that putting output files in the Output directory no longer
works, as QMTest does not build Output directories anymore (nor does the
test run in a separate subdirectory, anyway).

Chris Lattner ae509325d6 The simplifycfg pass should be able to turn stuff like: 
if (X == 4 || X == 7)
and
  if (X != 4 && X != 7)

into switch instructions.
