/* Specialized version of _PyObject_GenericGetAttrWithDict
specifically for the LOAD_METHOD opcode.
Return 1 if a method is found, 0 if it's a regular attribute
from __dict__ or something returned by using a descriptor
protocol.
`method` will point to the resolved attribute or NULL. In the
latter case, an error will be set.
