* libm/math/ef_scalb.c: Replace isnanf() (pre-C99 function call) with
isnan() (C99 macro).
* libm/math/wf_log.c: Ditto.
* libm/math/wf_j0.c: Ditto.
* libm/math/wf_sqrt.c: Ditto.
* libm/math/wf_pow.c: Ditto.
* libm/math/wf_fmod.c: Ditto.

* libm/math/wf_j1.c: Ditto.
* libm/common/sf_isnan.c: Add #include <ieeefp.h>, fix comment.
* libm/common/sf_isinf.c: Add #include <ieeefp.h>, adjust comment to
match that from s_isinf.c.
* libc/include/machine/ieeefp.h: Simplify isinf and isnan macros to
remove un-necessary extension use (in a similar manner to as was
recently done in math.h).
* libc/include/math.h: Remove isnanf and isinff prototypes (are in
ieeefp.h).
* libm/machine/spu/sf_isinf.c: Fix comment (remove <math.h>).
