db9147ae40 Add missing pcmp_XX methods for double/Packet2d 
This actually fixes an issue in unit-test packetmath_2 with pcmp_eq when it is compiled with clang. When pcmp_eq(Packet4f,Packet4f) is used instead of pcmp_eq(Packet2d,Packet2d), the unit-test does not pass due to NaN on ref vector.

a3298b22ec Implement vectorized versions of log1p and expm1 in Eigen using Kahan's formulas, and change the scalar implementations to properly handle infinite arguments. 
Depending on instruction set, significant speedups are observed for the vectorized path:
log1p wall time is reduced 60-93% (2.5x - 15x speedup)
expm1 wall time is reduced 0-85% (1x - 7x speedup)

The scalar path is slower by 20-30% due to the extra branch needed to handle +infinity correctly.

Full benchmarks measured on Intel(R) Xeon(R) Gold 6154 here: https://bitbucket.org/snippets/rmlarsen/MXBkpM

787f6ef025 Fix packed load/store for PowerPC's VSX 
The vec_vsx_ld/vec_vsx_st builtins were wrongly used for aligned load/store. In fact, they perform unaligned memory access and, even when the address is 16-byte aligned, they are much slower (at least 2x) than their aligned counterparts.

For double/Packet2d vec_xl/vec_xst should be prefered over vec_ld/vec_st, although the latter works when casted to float/Packet4f.

Silencing some weird warning with throw but some GCC versions. Such warning are not thrown by Clang.

4d29aa0294 Fix offset argument of ploadu/pstoreu for Altivec 
If no offset is given, them it should be zero.

Also passes full address to vec_vsx_ld/st builtins.

Removes userless _EIGEN_ALIGNED_PTR & _EIGEN_MASK_ALIGNMENT.

Removes unnecessary casts.

ff06ef7584 Eigen: Fix MSVC C++17 language standard detection logic 
To detect C++17 support, use _MSVC_LANG macro instead of _MSC_VER. _MSC_VER can indicate whether the current compiler version could support the C++17 language standard, but not whether that standard is actually selected (i.e. via /std:c++17).
