Our immediate concern is indeed just v7f, consistency says that whatever we
do to v7f we do to the others, however that depends entirely on others
requirements, we don't have a requirement to do anything to v7s and v7k so
can ignore those if needed.

For v7f, are you suggesting that we take the approach of adding a CPUSubType
option to pass information through to LLVM? Or that we may be able to get
rid of it entirely and forget about CPUSubType generation for v7f
specifically?
