creating shr and its tests for boost.simd
shr cover cmakelists correction
rshr is must still use arithmetic shift, this fit the existing tests and will be corrected later
shr in core with tests
deleting shri files. shri is now an alias of shr
replacing shri.hpp by shr.hpp in boost.simd
replacing shri.hpp by shr.hpp in core exponential
replacing shri.hpp by shr.hpp in core reduction
replacing shri.hpp by shr.hpp in core trigonometric
deleting shrai.hpp files
addin shrai tests to shift_right and correcting shrai.hpp includes
restore shr + formatting fix
make shr depend on shift_right, not the other way around + general clean-up
remove bogus files
remove shli, fuse into shift_left
missing include in shift_right
make shift_left on scalar floating use signed casting like other similar variants
make shift_left/shift_right/shr common code use generic instead of scalar or simd
restoring avx shift_right
fix altivec shift_right, add explicit call to splat for simd/scalar case
