[test] Re-add crash tests for getObjects:andKeys:count:
[test] Re-add crash tests for getObjects:andKeys:count:

On some platforms, when a new process is started, ARC’s autoreleased return value optimization is expected to fail the first time it is used in each linked dylib. StdlibUnittest takes care of warming up ARC for the stdlib (libswiftCore.dylib), but for Dictionary.swift, we also need to do it for Foundation, or there will be spurious leaks reported for tests immediately following a crash test.

Add the necessary dummy operations to setUp, and re-add the crash tests that were removed in #17862. (As separate tests this time, so they don’t hide leaks in non-crashing test parts.)
