allow constructing a auto_vec with a preallocation, and a possibly larger actual allocation size
This allows us to set the capacity of the vector when we construct it,
and still use a stack buffer when the size is small enough.
gcc/ChangeLog:
2017-05-13 Trevor Saunders <tbsaunde+gcc@tbsaunde.org>
* genrecog.c (int_set::int_set): Explicitly construct our
auto_vec base class.
* vec.h (auto_vec::auto_vec): New constructor.
