New analyser: Crash in attrs plugin on bad or deferred name #7098
Description
Both of these crash with the new analyser:
[case testTypeInAttrBad]
import attr
@attr.s
class C:
total = attr.ib(type=Bad)
[builtins fixtures/bool.pyi]
and
[case testTypeInAttrBad2]
import attr
@attr.s
class C:
total = attr.ib(default=func())
def func(): ...
[builtins fixtures/bool.pyi]
Both crash with an assertion error because plugin doesn't expect a placeholder in class symbol table. I didn't check dataclasses, but likely there is a similar issue.
