    • move several bitmaps from gc memory to the default obstack and use auto_bitmap · 8f9b31f7 
      These places where probably trying to use the default bitmap obstack,
but passing 0 to bitmap_initialize actually uses gc allocation.  In any
case they are all cleaned up before going out of scope so using
auto_bitmap should be fine.

    • allow constructing a auto_vec with a preallocation, and a possibly larger actual allocation size · a5c9f2b7 
      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.

    • store the bitmap_head within the auto_bitmap · a4d51bfb 
      This gets rid of one allocation per bitmap.  Often the bitmap_head is
now on the stack, when it isn't its part of some other struct on the
heap instead of being refered to by that struct.  On 64 bit platforms
this will increase the size of such structs by 24 bytes, but its an over
all win since we don't need an 8 byte pointer pointing at the
bitmap_head.  Given that the auto_bitmap owns the bitmap_head anyway we
know there would never be a place where two auto_bitmaps would refer to
the same bitmap_head object.

	* bitmap.h (class auto_bitmap): Change type of m_bits to
	bitmap_head, and adjust ctor / dtor and member operators.
