Jingyue Wu e84f671830 [JumpThreading] make jump threading respect convergent annotation. ... Summary: JumpThreading shouldn't duplicate a convergent call, because that would move a convergent call into a control-inequivalent location. For example, if (cond) { ... } else { ... } convergent_call(); if (cond) { ... } else { ... } should not be optimized to if (cond) { ... convergent_call(); ... } else { ... convergent_call(); ... } Test Plan: test/Transforms/JumpThreading/basic.ll Patch by Xuetian Weng.
