Is this ready for review?

If not, perhaps mark it as a "draft" for now.

Looks promising. Will need some tests for the new output format.

One problem is that some instructions are too long(like PRECALL_BUILTIN_FAST_WITH_KEYWORDS), do I need to increase _OPNAME_WIDTH

defadaptive_test(a, b): c=a+bprint(c.__class__)

Exec dis(adaptive_test):

 30 0 RESUME 0 31 2 LOAD_FAST 0 (a) 4 LOAD_FAST 1 (b) 6 BINARY_OP 0 (+) 10 STORE_FAST 2 (c) 32 12 LOAD_GLOBAL 1 (NULL + print) 24 LOAD_FAST 2 (c) 26 LOAD_ATTR 1 (__class__) 36 PRECALL 1 40 CALL 1 50 POP_TOP 52 LOAD_CONST 0 (None) 54 RETURN_VALUE 

Exec dis(adaptive_test, adaptive=True):

 30 0 RESUME_QUICK 0 31 2 LOAD_FAST__LOAD_FAST 0 (a) 4 LOAD_FAST 1 (b) 6 BINARY_OP_ADD_INT 0 (+) 10 STORE_FAST 2 (c) 32 12 LOAD_GLOBAL_BUILTIN 1 (NULL + print) 24 LOAD_FAST 2 (c) 26 LOAD_ATTR_SLOT 1 (__class__) 36 PRECALL_BUILTIN_FAST_WITH_KEYWORDS 1 40 CALL_ADAPTIVE 1 50 POP_TOP 52 LOAD_CONST 0 (None) 54 RETURN_VALUE

Already add some test cases for quicken code in the dis.

Could you remove the changes to _testinternalcapi, so we don't need to export the _PyCode_Quicken function.
