I keep the issue open until the 3.6 branch is reopened for regular bug fixes, 
like this one. Then I will backport the fix to 3.6.

[issue28770] Update python-gdb.py for fastcalls

[STINNER Victor]

New submission from STINNER Victor:

Python 3.6 has a new C calling convention: "fast calls".

python-gdb.py was disabled when compact dict was merged, see issue #27350.

Sadly, I missed that fast calls also broke python-gdb.py.

Attached patch fixes python-gdb.py, but I failed to fix test_gdb.py. With fast 
calls and patched python-gdb.py, python-gdb.py is now able to detect the Python 
frame of the call to the builtin id() function. It's a new feature compared to 
Python 3.5, but test_gdb.py should be updated to handle that.

I will try to fix that later, but in the meanwhile I was interrupted because 
the fix for compact dict in python-gdb.py failed on buildbots, see:
