[GSoC] Question about the implementation of vec.h

[Roman Gareev]

Dear gcc contributors,

could you please answer a few questions about the implementation of
vec.h? Should we always use “create” to initialize, for example,
vec<tree_node*> or is it possible to do it using “safe_grow_cleared”
or a similar function? There is "vec_safe_grow_cleared", which works
with vec<T, A, vl_embed>. Is there a way to use it with
vec<tree_node*>?

I would be very grateful for your comments.
