 The goal of DeterministicBuilds (#4012) was to get ABI-compatible binaries
 given the same sources, flags and the environment.
 There's a stronger goal of getting bit-for-bit identical binaries and this
 ticket will track that.

 Known causes of binary nondeterminism:

 * Unique comparison
 * Uniques converted to strings for symbol names
 * everything else from #4012
