527cd19c3d Make dbl-64 atan and tan into weak aliases.
This patch converts the dbl-64 implementations of atan and tan into
weak aliases of __atan and __tan, in preparation for making them use
libm_alias_double.  Consequent changes are made to the x86_64
multiarch versions wrapping round them (with the dbl-64 functions,
like other such functions, being made not to define their aliases at
all if __atan or __tan are defined as macros by an including file).

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

	* sysdeps/ieee754/dbl-64/s_atan.c (atan): Rename to __atan and
	define as weak alias of __atan.  Do not define any aliases if
	[__atan].
	[NO_LONG_DOUBLE] (__atanl): Define as strong alias of __atan.
	[NO_LONG_DOUBLE] (atanl): Define as weak alias of __atanl.
	* sysdeps/ieee754/dbl-64/s_tan.c (tan): Rename to __tan and define
	as weak alias of __tan.  Do not define any aliases if [__tan].
	[NO_LONG_DOUBLE] (__tanl): Define as strong alias of __tan.
	[NO_LONG_DOUBLE] (tanl): Define as weak alias of __tanl.
	* sysdeps/x86_64/fpu/multiarch/s_atan-avx.c (atan): Rename to
	__atan.

57a72fa350 x86-64: Add FMA multiarch functions to libm
This patch adds multiarch functions optimized with -mfma -mavx2 to libm.
e_pow-fma.c is compiled with $(config-cflags-nofma) due to PR 19003.

	* sysdeps/x86_64/fpu/multiarch/Makefile (libm-sysdep_routines):
	Add e_exp-fma, e_log-fma, e_pow-fma, s_atan-fma, e_asin-fma,
	e_atan2-fma, s_sin-fma, s_tan-fma, mplog-fma, mpa-fma,
	slowexp-fma, slowpow-fma, sincos32-fma, doasin-fma, dosincos-fma,
	halfulp-fma, mpexp-fma, mpatan2-fma, mpatan-fma, mpsqrt-fma,
	and mptan-fma.
