Now the failing tests are reduced to:

33 suites passed, 3 failed, 36 total
    tests/neg/syntax-error-recovery.scala failed
    tests/neg/multi-file-error failed
    tests/run/enrich-gentraversable.scala failed
    tests/run/enrich-gentraversable.scala failed

The first two seem to be a problem in my local setup. So there should be one last issue remaining.

fixes #19988

The issue is caused by the change of class hierarchy in Scala 2 library
CC: `SeqView` no longer extends `SeqOps`. To fix this we have to copy
methods from `SeqOps` to `SeqViewOps`. Similar to what is done in
#19873.
