*	Replace all usages of Blaze's Preconditions class with guava.	tomlu	2017-11-09
\| \| \| \| \| \| \| \|	Blaze had its own class to avoid GC from varargs array creation for the precondition happy path. Guava now (mostly) implements these, making it unnecessary to maintain our own. This change was almost entirely automated by search-and-replace. A few BUILD files needed fixing up since I removed an export of preconditions from lib:util, which was all done by add_deps. There was one incorrect usage of Preconditions that was caught by error prone (which checks Guava's version of Preconditions) that I had to change manually. PiperOrigin-RevId: 175033526

	reverseDepsToConsolidate field in InMemoryNodeEntry. As part of that, revamp our logic of how we store pending operations: store adds bare on initial evaluations, and checks bare on incremental evaluations and operations on done nodes. This should improve performance in two ways: BuildingState loses two fields, saving working memory intra-build. Storing pending reverse dep operations bare also saves memory intra-build. Note that neither of these changes helps resting memory state, only while a node is still evaluating. Because of this, we can simplify ReverseDepsUtil a bit, making ReverseDepsUtilImpl a static class, which it always wanted to be (what it really wants to be is a superclass of InMemoryNodeEntry, but I don't want to spend the object alignment bits). Finally, this makes it pretty tempting to get rid of BuildingState altogether on initial evaluations. We'd still keep DirtyBuildingState, but we could save another ~24 bytes by storing BuildingState's one remaining field, signaledDeps, directly inside InMemoryNodeEntry. -- PiperOrigin-RevId: 151048879 MOS_MIGRATED_REVID=151048879
