Call math_opt_barrier inside if

Since floating-point operation may trigger floating-point exceptions,
we call math_opt_barrier inside if to prevent code motion.

[BZ #19465]
* sysdeps/ieee754/dbl-64/s_fma.c (__fma): Call math_opt_barrier
inside if.
* sysdeps/ieee754/ldbl-128/s_fmal.c (__fmal): Likewise.
* sysdeps/ieee754/ldbl-96/s_fma.c (__fma): Likewise.
* sysdeps/ieee754/ldbl-96/s_fmal.c (__fmal): Likewise.
