Joseph Myers 71223ef909 Use ceil functions not __ceil functions in glibc libm.
Continuing the move to use, within libm, public names for libm
functions that can be inlined as built-in functions on many
architectures, this patch moves calls to __ceil functions to call the
corresponding ceil names instead, with asm redirection to __ceil when
the calls are not inlined.

Tested for x86_64, and with build-many-glibcs.py.

Joseph Myers 15ff490014 Use libm_alias_float for aarch64.
Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes aarch64 libm function implementations use
libm_alias_float to define function aliases.

Tested with build-many-glibcs.py for aarch64-linux-gnu that installed
stripped shared libraries are unchanged by the patch.

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.

Marcus Shawcroft 75eff3fe90 Relocate AArch64 from ports to libc.
This patch moves the AArch64 port to the main sysdeps hierarchy.  The
move is essentially:

  git mv ports/sysdeps/aarch64 sysdeps/aarch64
  git mv ports/sysdeps/unix/sysv/linux/aarch64 sysdeps/unix/sysv/linux/aarch64

The README is updated and I've updated ChangeLog.aarch64 along the
lines of the ARM move.  The AArch64 build has been tested to confirm
that there were no changes in objdump -dr output or the shared
objects.
