x86-64: Add vector expm1/expm1f implementation to libmvec

Browse Source 
Implement vectorized expm1/expm1f containing SSE, AVX, AVX2 and
AVX512 versions for libmvec as per vector ABI.  It also contains
accuracy and ABI tests for vector expm1/expm1f with regenerated ulps.

/*
* ALGORITHM DESCRIPTION:
* After computing exp(x) in high-low parts, an accurate computation is performed to obtain exp(x)-1
* Typical exp() implementation, except that:
* - tables are small (16 elements), allowing for fast gathers
* - all arguments processed in the main path
* - final VSCALEF assists branch-free design (correct overflow/underflow and special case responses)
* - a VAND is used to ensure the reduced argument |R|<2, even for large inputs
* - RZ mode used to avoid oveflow to +/-Inf for x*log2(e); helps with special case handling
*

/*
* ALGORITHM DESCRIPTION:
* After computing exp(x) in high-low parts, an accurate computation is performed to obtain exp(x)-1
* Typical exp() implementation, except that:
* - tables are small (32 elements), allowing for fast gathers
* - all arguments processed in the main path
* - final VSCALEF assists branch-free design (correct overflow/underflow and special case responses)
* - a VAND is used to ensure the reduced argument |R|<2, even for large inputs
* - RZ mode used to avoid oveflow to +/-Inf for x*log2(e); helps with special case handling
*
