cpython-lru_cache-weakref: Python/ceval.c annotate

annotate Python/ceval.c @ 1354:fccd415e2eb8 legacy-trunk

* bltinmodule.c: removed exec() built-in function. * Grammar: add exec statement; allow testlist in expr statement. * ceval.c, compile.c, opcode.h: support exec statement; avoid optimizing locals when it is used * fileobject.{c,h}: add getfilename() internal function.
