Skip 3 gorepo tests that attempt to pass unsupported flags:

  - fixedbugs/issue46938.go tests checkptr mode, which is unapplicable
    to GopherJS.
  - fixedbugs/issue47928.go tests //go:nointerface pragma, which is not
    a part of the Go spec.
  - fixedbugs/issue49665.go will be re-enabled in Go 1.19, where -G=3
    flag is removed; it would have passed if not for the unsupported
    flag.
