Add a vect_align_stack_vars target selector
This patch adds a target selector to say whether it's possible to
align a local variable to the target's preferred vector alignment.
This can be false for large vectors if the alignment is only
a preference and not a hard requirement (and thus if there is no
need to support a stack realignment mechanism).
