Precompiled hermes binaries? about hermes

[Urcra]

Hey just noticed that the tools from https://github.com/facebook/hermes/blob/master/doc/BuildingAndRunning.md#other-tools are not included in the prebuilt binaries. Would be awesome if you could add them to a release 😄

We already provide binaries for macOS, Linux and Windows (all x86_64) through GitHub releases and NPM.

Is that what you're looking for, or do you have other platforms in mind?

That's helpful, thanks!

GoogleChromeLabs/jsvu#74 adds hermes support to jsvu, based on the following assumptions:

• Amongst the jsvu-supported platforms (i.e. mac64, linux32, linux64, win32, win64), hermes only provides only mac64, linux64, and win64 builds.
• The ['dist-tags'].latest field in https://registry.npmjs.org/hermes-engine always points to the latest available Hermes version number.
• The URL format for the GitHub download links won't change over time.
• The dir/file structure of the provided tarball contents won't change over time.

If any of these assumptions seem likely to change in the future, please let us know so we can come up with an alternate approach.

Along the way, I noticed that the npm tarballs (e.g. https://registry.npmjs.org/hermesvm/-/hermesvm-0.1.0.tgz) do not contain the DLLs for the Windows version. The GitHub tarballs do. Let me know if you'd like me to file this as a separate issue.

@mathiasbynens Thanks for noticing! This issue is fine.

The NPM ICU dll issue was fixed in 02ec02a, though it still depends on the MSVC++2015 Redistributable though. All future NPM releases should include them, as well as the precompiled binaries.
