Symbols js_ast.SymbolMap
// We should avoid traversing all files in the bundle, because the linker
// should be able to run a linking operation on a large bundle where only
// a few files are needed (e.g. an incremental compilation scenario). This
// holds all files that could possibly be reached through the entry points.
// If you need to iterate over all files in the linking operation, iterate
// over this array. This array is also sorted in a deterministic ordering
// to help ensure deterministic builds (source indices are random).
ReachableFiles []uint32
// This maps from unstable source index to stable reachable file index. This
// is useful as a deterministic key for sorting if you need to sort something
// containing a source index (such as "js_ast.Ref" symbol references).
