Raymond Hettinger f606f87b31 Introduced macros for a simple opcode prediction protocol. ...

Applied to common cases:
    COMPARE_OP is often followed by a JUMP_IF.
    JUMP_IF is usually followed by POP_TOP.

Shows improved timings on PyStone, PyBench, and specific tests
using timeit.py:
    python timeit.py -s "x=1" "if x==1: pass"
    python timeit.py -s "x=1" "if x==2: pass"
    python timeit.py -s "x=1" "if x: pass"
    python timeit.py -s "x=100" "while x!=1: x-=1"

Potential future candidates:
    GET_ITER predicts FOR_ITER
    FOR_ITER predicts STORE_FAST or UNPACK_SEQUENCE

Also, applied missing goto fast_next_opcode to DUP_TOPX.
