I need to restructure this.  As I noted over in https://reviews.llvm.org/D76176, we have a problem for the assembler use case w/inserting prefixes between previous data encoded prefixes and the instruction.  This isn't relevant for the compiler (since we have the suppression mechanism), but we need to structure this such that only the compiler enables this feature.  I'm very unhappy about how ugly that is, but I don't see a way around it.
