Requiring that ops don't use a stack frame doesn't seem like a realistic
constraint.

The use of soft-float should be a host decision, not a target decision.
All targets should be converted to use the softfloat.h interface. Hosts can
then choose to use with the softfloat library or the native implementation
depending on the host FP capabilities.
