Summary: CALL_ATTR opcode

Initial Comment:
The result of the PyCore sprint of me and Brett: the CALL_ATTR opcode (LOAD_ATTR and CALL_FUNCTION combined) that skips the PyMethod creation and destruction for classic classes (but not newstyle classes, yet.)

The code is somewhat rough yet, it needs commenting, some renaming, and most importantly testing. It seems to work, however, and provides between a 35% and 5% speedup. (5% in 'average' code, up to 35% in instance method calls and instance creation alone.) It also needs to be updated to include newstyle classes. I will likely work on this on the flight home.
