  -----------
  [orc-rt] Move ErrorTest death tests to an ErrorDeathTest suite. (#209476)

GoogleTest recommends putting death tests in a suite whose name ends in
"DeathTest": it runs those suites before all others, which avoids the
fork-after-threads hazard that can make death tests flaky.

Move the nine EXPECT_DEATH tests in ErrorTest.cpp from the ErrorTest
suite to a new ErrorDeathTest suite. Only the suite name changes; the
test bodies are untouched.
