rustbuild: Pass -Zsave-analysis during tests

alexcrichton · alexcrichton · commit 008ed188ce48 · 2019-09-23T09:34:44.000-07:00
This is needed to ensure that the crates during a normal build are
shared with the crates during testing, otherwise they'll end up hasing
differently and we'll recompile crates like `core` during tests.
