9931b1f7a4785b6a17fb87b81a3546d61d0cbca1 switched this to checking for the two specific subtargets, instead of the dedicated feature. This broke supporting functions which force added the feature when emitting targets that do not actually support them. This stil does not work for the targets that use the gfx6/7 or gfx10 encodings.
