[SLP]Improve reordering for consts, splats and ops from same nodes + improved analysis.

Improved detection of const/splat candidates, their matching and analysis of instructions from same nodes.

MultiSource/Benchmarks/DOE-ProxyApps-C++/miniFE/miniFE - small
reordering
External/SPEC/CINT2006/464.h264ref/464.h264ref - small better code after
reordering
MultiSource/Applications/JM/lencod/lencod - smaller code with less
shuffles
MultiSource/Applications/JM/ldecod/ldecod - same
External/SPEC/CFP2017rate/511.povray_r/511.povray_r - 2 extra loads
vectorized, smaller code
External/SPEC/CFP2017rate/538.imagick_r/538.imagick_r - better code,
size increased because of more constant vectors.
External/SPEC/CFP2017speed/638.imagick_s/638.imagick_s - same
External/SPEC/CFP2017rate/526.blender_r/526.blender_r - small change in
the vectorized code, some code a bit better, some a bit worse.
