We can only PHI translate instructions. In our attempt to PHI translate a bitcast, we attempt to translate its operand; however, the operand might be an argument or a global instead of an instruction. Benignly bail out when this happens. This fixes PR24397. Differential Revision: http://reviews.llvm.org/D11879 llvm-svn: 244418
