x86-64: Add vector log1p/log1pf implementation to libmvec
Implement vectorized log1p/log1pf containing SSE, AVX, AVX2 and AVX512 versions for libmvec as per vector ABI. It also contains accuracy and ABI tests for vector log1p/log1pf with regenerated ulps. Reviewed-by: H.J. Lu <hjl.tools@gmail.com>

*
|

* 1+x = 2^k*(xh + xl) is computed in high-low parts; xh in [1,2)
|
||||
* Get short reciprocal approximation Rcp ~ 1/xh
|

* R = (Rcp*xh - 1.0) + Rcp*xl
|

* log1p(x) = k*log(2.0) - log(Rcp) + poly(R)
|

* log(Rcp) is tabulated
