[swift-dev] Differences between Xcode official toolchains and tagged releases from repository

[Xavier Jurado]

Thanks for the hint! When I built the toolchain I modified the
"mixin_lightweight_assertions" preset locally to use "no-assertions" and
"swift-assertions", thinking it was the appropriate combination based on a
FIXME comment. I will try building it again with only "no-assertions" and
report back.
