Fixes Threading2 test on mips no-snap bots
(http://build.chromium.org/p/client.v8/builders/V8%20Mips%20-%20big%20endian%2...).
Due to differing test order on mips (caused by toolchain static constructor
initialization differences), InternalFieldCallback test fell exactly into this
gap where incremental marking GC had started, preventing a full GC, though test
required full GC to pass.

Thanks for the fix.
