17226100c5 Fix a circular dependency regarding pshift* functions and GenericPacketMathFunctions. 
Another solution would have been to make pshift* fully generic template functions with
partial specialization which is always a mess in c++03.

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.

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

Removes userless _EIGEN_ALIGNED_PTR & _EIGEN_MASK_ALIGNMENT.

Removes unnecessary casts.
