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.

d55d392e7b Fix bugs in log1p and expm1 where repeated using statements would clobber each other. 
Add specializations for complex types since std::log1p and std::exp1m do not support complex.

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).
