Michael Collison 5062680c60 aarch64: Implement math acceleration via builtins
This patch converts asm statements into builtins for AArch64.  As an
example for the file sysdeps/aarch64/fpu/s_ceil.c, we convert the
function from

double
__ceil (double x)
{
  double result;
  asm ("frintp\t%d0, %d1" :
       "=w" (result) : "w" (x) );
  return result;
}

into

double
__ceil (double x)
{
  return __builtin_ceil (x);
}

Tested on aarch64-linux-gnu with gcc-4.9.4 and gcc-6.
