LIRFrameState locals[0]

[Deneau, Tom]

I've noticed that sometimes when I get a DeoptimizationNode, the attached LIRFrameState for locals[0] sometimes has a type of illegal.  Why might this be?

info.topFrame.numLocals = 4
info.topFrame.values[0].kind = "illegal"
info.topFrame.values[1].kind = "Object"
info.topFrame.values[2].kind = "int"
info.topFrame.values[3].kind = "int"
