Fix gcc unused value warning in FreeBSD simd.h

Browse Source 
The macros `simd_stat_init()` and `simd_stat_fini()` in FreeBSD's
`simd.h` are defined as zero, but they are actually only used as
statements. Replace the definitions with `do {} while (0)` instead, to
avoid gcc `-Wunused-value` warnings.
