[swift-dev] Validation test failures on swift-4.0-branch

[Vivian Kong]

While running validation tests on swift-4.0-branch on Ubuntu 16.04, I got
~20 failures but I don't see them on ci.swift.org.

Wondering if there are any build settings/pre-reqs I might be missing.  I'm
doing a RelWithDebInfo (-r) build.

      Failing Tests (22):
          Swift-Unit ::
      runtime/SwiftRuntimeTests/TestOpaqueExistentialBox.test_assignWithCopy_indirect_indirect
