f96418de05 Issue #24870: Optimize the ASCII decoder for error handlers: surrogateescape, 
ignore and replace. Initial patch written by Naoki Inada.

The decoder is now up to 60 times as fast for these error handlers.

Add also unit tests for the ASCII decoder.

5783fd2c58 Issue #24999: In longobject.c, use two shifts instead of ">> 2*PyLong_SHIFT" to 
avoid undefined behaviour when LONG_MAX type is smaller than 60 bits.

This change should fix a warning with the ICC compiler.

4a0d1e7c36 odictobject.c: fix compiler warning 
PyObject_Length() returns a P_ssize_t, not an int. Use a Py_ssize_t to avoid
overflow.

56f6e76c68 Issue #15989: Fixed some scarcely probable integer overflows. 
It is very unlikely that they can occur in real code for now.

99bb14bf0c type_call() now detect bugs in type new and init 
* Call _Py_CheckFunctionResult() to check for bugs in type
  constructors (tp_new)
* Add assertions to ensure an exception was raised if tp_init failed
  or that no exception was raised if tp_init succeed

Refactor also the function to have less indentation.

ac2ef65c32 Make the unicode equality test an external function rather than in-lining it. 
The real benefit of the unicode specialized function comes from
bypassing the overhead of PyObject_RichCompareBool() and not
from being in-lined (especially since there was almost no shared
data between the caller and callee).  Also, the in-lining was
having a negative effect on code generation for the callee.
