	// When mangling property names, call this function with a callback and do

	// This is a callback for determinism reasons. We may be building multiple
	// entry points in parallel that are supposed to share a single cache. We
	// don't want the order that each entry point mangles properties in to cause
	// the output to change, so we serialize the property mangling over all entry
	// points in entry point order. However, we still want to link everything in
	// parallel so only property mangling is serialized, which is implemented by
	// this function blocking until the previous entry point's property mangling
	// has finished.

type ProcessedDefines 

type ProcessedDefines struct {
	IdentifierDefines map[string]DefineData
	DotDefines        map[string][]DotDefine

func ProcessDefines 

func ProcessDefines(userDefines map[string]DefineData) ProcessedDefines

This transformation is expensive, so we only want to do it once. Make sure to only call processDefines() once per compilation. Unfortunately Golang doesn't have an efficient way to copy a map and the overhead of copying all of the properties into a new map once for every new parser noticeably slows down our benchmarks.
