cmd/compile: compilation results for generic types are affected by the filename #51048
Description
What version of Go are you using (go version)?
$ go version go version go1.18beta2 linux/arm64
Does this issue reproduce with the latest release?
Yes, it can be reproduced in the latest beta version. The minimal reproducible code I put at https://github.com/sxyazi/awesomeProject
What operating system and processor architecture are you using (go env)?
go env Output

What did you do?
I executed go test, but it got an error. When I changed the file name from foo.go to hello.go, it worked correctly again. I suspect it has something to do with the compilation order of the filenames.
What did you expect to see?
Pass the test correctly
What did you see instead?
./foo.go:14:13: T does not implement []E ([]E is not an interface)
