Log:
Handle more SLP constant and extern definitions for variable VF

This patch adds support for vectorising SLP definitions that are
constant or external (i.e. from outside the loop) when the vectorisation
factor isn't known at compile time.  It can only handle cases where the
number of SLP statements is a power of 2.
