Wrapping all setXXXAction() calls for f16 with a guard against soft-float,
which should make sure that no custom handlings that emit vector / fp
instructions are reached.
Soft-float fails with calls to non-existing library functions it seems,
including calls to the conversion functions we are now using, except with args
in GPRs instead.
