Note that different tests may need different IEEE features, though some 
such cases are already handled specially anyway - so be clear on what 
target properties such a keyword actually relates to.  (E.g. 
fenv_exceptions already exists for tests needing floating-point 
exceptions; tests that don't work on SPU because of the way its 
single-precision format deviates from IEEE are skipped specifically for 
spu-*-*; tests handling IBM long double specially as needed.)
