\| \| \| \| \| \| \| \| \|	of sin/cos and call it instead of falling back to std::sin/std::cos. This makes both the small and huge argument cases faster because: - for small inputs this removes the last pselect - for large inputs only the reduction part follows a scalar path, the rest use the same SIMD path as the small-argument case.

*	bug #1652: implements a much more accurate version of vectorized sin/cos. ↵	Gael Guennebaud	2019-01-09
\| \| \| \| \| \| \|	This new version achieve same speed for SSE/AVX, and is slightly faster with FMA. Guarantees are as follows: - no FMA: 1ULP up to 3pi, 2ULP up to sin(25966) and cos(18838), fallback to std::sin/cos for larger inputs - FMA: 1ULP up to sin(117435.992) and cos(71476.0625), fallback to std::sin/cos for larger inputs

*	Make sure that psin/pcos return number in [-1,1] for large inputs (though ↵	Gael Guennebaud	2018-12-23
\| \| \| \|	sin/cos on large entries is quite useless because it's inaccurate)

*	Update pshiftleft to pass the shift as a true compile-time integer.	Gael Guennebaud	2018-11-27

*	Unify SSE/AVX psin functions.	Gael Guennebaud	2018-11-27
\| \| \| \| \| \| \| \|	It is based on the SSE version which is much more accurate, though very slightly slower. This changeset also includes the following required changes: - add packet-float to packet-int type traits - add packet float<->int reinterpret casts - add faster pselect for AVX based on blendv
*	Unify SSE and AVX pexp for double.	Gael Guennebaud	2018-11-26

*	First step toward a unification of packet log implementation, currently only ↵	Gael Guennebaud	2018-11-26
	SSE and AVX are unified. To this end, I added the following functions: pzero, pcmp_*, pfrexp, pset1frombits functions.
