[PATCH] D76192: Use maximum compression when packaging release tarballs.

[Dimitry Andric via Phabricator via llvm-commits]

dim created this revision.
dim added reviewers: hans, tstellar, rovka.
Herald added a project: LLVM.

Since a full run of test-release.sh takes many hours (at least on my
poor systems), we might as well spend some extra time compressing the
tarball, in return for a quite a bit of gains for uploading and
downloading it.

As an example, the 10.0.0-rc4 .tar.xz tarball shrinks from 465MiB to
306MiB, about 52% smaller.
