This refactors code to arrange that for loop SLP we pass in the SLP
node and instance to the vectorizable_* functions also at analysis
phase (not only at transform phase).
Bootstrapped and tested on x86_64-unknown-linux-gnu, applied to trunk.

This does some more cleanup and refactoring with two fixes, the
pure slp compute in vect_analyze_loop_operations was failing
to look at pattern stmts and the vect_is_slp_reduction hunk makes
reduction detection fail because the pattern state changes in
between reduction detection and vectoriztaion
