  Speed-up dictionary constructor by about 10%.

  New opcode, STORE_MAP saves the compiler from awkward stack manipulations
  and specializes for dicts using PyDict_SetItem instead of PyObject_SetItem.

  Old disassembly:
                0 BUILD_MAP                0
                3 DUP_TOP
                4 LOAD_CONST               1 (1)
                7 ROT_TWO
                8 LOAD_CONST               2 ('x')
               11 STORE_SUBSCR
               12 DUP_TOP
               13 LOAD_CONST               3 (2)
               16 ROT_TWO
               17 LOAD_CONST               4 ('y')
               20 STORE_SUBSCR

  New disassembly:
                0 BUILD_MAP                0
                3 LOAD_CONST               1 (1)
                6 LOAD_CONST               2 ('x')
                9 STORE_MAP
               10 LOAD_CONST               3 (2)

  Give meaning to the oparg for BUILD_MAP:  estimated size of the dictionary.

  Allows dictionaries to be pre-sized (upto 255 elements) saving time lost
  to re-sizes with their attendant mallocs and re-insertions.

  Has zero effect on small dictionaries (5 elements or fewer), a slight
  benefit for dicts upto 22 elements (because they had to resize once
  anyway), and more benefit for dicts upto 255 elements (saving multiple
  resizes during the build-up and reducing the number of collisions on
  the first insertions).  Beyond 255 elements, there is no addional benefit.
