[New-bugs-announce] [issue38083] Minor improvements in asdl_c.py and Python-ast.c

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

* Use the const qualifier for constant C strings. This will save memory for their copy in a modifiable memory.
* Intern field and attribute names. This will save time, as comparing interned strings is faster.
* Temporary incref a borrowed reference to a list item. Arbitrary Python code can be executed when convert an item to C values. The list containing the item can be modified and the reference can became dead if not incref it.
