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.

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.

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)

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).

d1eaebef49 The simplifycfg pass should be able to turn stuff like:
if (X == 4 || X == 7)
and
  if (X != 4 && X != 7)

into switch instructions.
