Clean up snapshot test cases (#3091)

* Clean up snapshot test cases:
- Drop 32bit snapshots
- Update iOS 9 snapshots and move some others to the correct directory
- Remove `setUp` overrides in subclasses of `ASLayoutSpecSnapshotTestCase` that set `recordMode` flag. Doing so in multiple places make it difficult to enable/dis
able the flag for all layout spec test cases. It can always be overridden locally if need
to.
- Fix BUCK build

* Fix testThatOnDidLoadThrowsIfCalledOnLoadedOffMain of ASDisplayNodeTests
