* AMDGPU/SI: Annotate Loops with Constant Condition in SIAnnotateControlFlow pass.Changpeng Fang2016-02-121-0/+24
Summary: It is possible that the loop condition can be a boolean constant (infinite loop, for example). So we sould handle constant condition in annotating a loop. This patch adds this functionality to support annotating constant condition.
