Chris Lattner d802347a2e new testcase for a simple optimization that simplifycfg is about to do. 
All CFG edges to DEAD should be eliminated.

Chris Lattner 90970609f2 add another testcase to make sure it gets turned into a switch (answer: yes it does)

Chris Lattner 72a406eb14 Add new test to make sure simplifycfg doesn't leave around trivially 
dead instructions.

Chris Lattner 1c7efba2bd 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 f380445185 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 dcf3a6b124 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 2942e6356b 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).
