InstrumentBranchesPhaseTest

[Andrew Haley]

I'm baffled by InstrumentBranchesPhaseTest.  I'm getting a failure here:

        Assert.assertTrue(stackOutput.contains("[bci: 4]\n[0] state = ELSE(if=0#, else=1#)"));

but the output is:

{com.oracle.graal.truffle.test.InstrumentBranchesPhaseTest$SimpleIfTestNode.execute(InstrumentBranchesPhaseTest.java:48) [bci: 4]=[0] state = NONE(if=0#, else=0#)}

I don't know what this test does, and I don't understand how any of
this might be AArch64-specific.

Thanks,

Andrew.
