[LLVMbugs] Rd and Rm should be different in mul (for ARM target)

This was a hardware restriction on early ARM chips that has been  
removed in later ones.  You need to tell the assembler that your  
target chip is one of the current ones somehow (or you may need a  
later assembler).  In some assembler versions at least, this message  
is only a warning and the assembled code is correct.
