Merge r168147 from trunk:
Constant::IsThreadDependent(): Use dyn_cast<Constant> instead of cast
It turns out that the operands of a Constant are not always themselves
Constant. For example, one of the operands of BlockAddress is
BasicBlock, which is not a Constant.
This should fix the dragonegg-x86_64-linux-gcc-4.6-test build which
broke in r168037.
