[PATCH] D145884: test-release.sh: build projects and runtimes lists with semicolons

[Dimitry Andric via Phabricator via llvm-commits]

dim updated this revision to Diff 508399.
dim added a comment.

Add another build optimization: in the first phase, we only need to
build a working clang compiler, which is capable of building itself and
the runtimes in the second phase. Therefore, we can skip building any of
the runtimes in the first phase.
