Matthew Dempsky efa9efe8e4 cmd/compile: silence unnecessary unsafe error
If n.Type==nil after typechecking, then we should have already
reported a more useful error somewhere else. Just return 0 in
evalunsafe without trying to do anything else that's likely to cause
problems.

Also, further split out issue7525.go into more test files, because
cmd/compile reports at most one typechecking loop per compilation
unit.

Fixes #22351.
