Most probably C compilers inline functions, but just to be sure, I'd convert them into the macros: 

#define to_raw_bits(d) *((EIF_NATURAL_64*)&(d))
 
#define eif_is_nan_bits(value) ((value & ~RTU64C(0x8000000000000000)) > RTU64C(0x7ff0000000000000))
 
#define eif_is_nan(v) ((*((EIF_NATURAL_64 *)&(v)) & ~RTU64C(0x8000000000000000)) > RTU64C(0x7ff0000000000000))

Does it affect the benchmarks?
