bpo-15817: gdbinit: Document commands after defining them (GH-15021)
The gdb manual[1] says the following for "document":
The command commandname must already be defined.
[1] https://sourceware.org/gdb/current/onlinedocs/gdb/Define.html
And indeed when trying to use the gdbinit file with gdb 8.3, I get:
.../cpython/Misc/gdbinit:17: Error in sourced command file:
Undefined command: "pyo". Try "help".
Fix this by moving all documentation blocks after the define blocks.
This was introduced in GH-6384.
