[issue2262] Helping the compiler avoid memory references in PyEval_EvalFrameEx

[Skip Montanaro]

Skip Montanaro <skip at pobox.com> added the comment:

Pybench doesn't show much difference for me, about 0.1% better on minimum
times.  A few tests are quite a bit worse (> 10%) with the patch
(Recursion, SimpleFloatArithmetic, StringPredicates, TryFinally).  A few
are quite a bit better (CompareFloatsIntegers, CompareIntegers,
DictWithFloatKeys).
