 2020-08-17 21:32:47 +02:00
Tobias Koppers e16bdfda6c refactor used exports analysis, hashing, code generation, optimizations 
to keep track of runtimes, used exports depending on runtime

modules can have different hashes and generated code depending on runtime
chunks are only considered as equal for MergeDuplicateChunks and SplitChunks when exports used in contained modules are equal
added `optimization.usedExports: "global"` to opt-out from used exports analysis per runtime
added `splitChunks.usedExports` and `splitChunks.cacheGroups[x].usedExports` to enable/disable used exports comparing for modules
`splitChunks.usedExports` defaults to `true` in production
