New Revision: 25722

Added:
   pypy/dist/pypy/translator/microbench/test_dict.py
Log:

add a few dictionary (r_dict) related performance tests

comparing a default pypy-c and cpython-2.4.1 gives on my machine: 

 3.30x slower on test_dict.test_dict_setitem()
 3.50x slower on test_dict.test_dict_raw_range()
 4.43x slower on test_dict.test_dict_class_dict_getmethod()
 5.18x slower on test_dict.test_dict_getitem()
 7.71x slower on test_dict.test_dict_instance_setnewattr_instance_dict()
 8.00x slower on test_dict.test_dict_instance_getattr_instance_dict()
 8.14x slower on test_dict.test_dict_instance_setattr_instance_dict()
