Minor changes to the blaze command line executed by our autoupdate
scripts:
- Don't change the convenience symlinks. Running autoupdate shouldn't
cause `./bazel-bin/...` to switch to running a different binary.
- Don't produce so much spam. Bazel will still log its build progress if
necessary, and still report compile and runtime errors, but won't
produce half a dozen lines of INFO at the start of the command.
This migrates explorer tests to file_test, using the new --autoupdate
functionality. Per discussion, the trace tests that were using "not"
output are mostly migrated to checking full output. The main exception
is tests that were including trace output from the prelude: the prelude
output is pretty long (multiple MB already) and I think it wasn't the
intent to include, only trace output from the small program.
This is the remaining use of lit support, so the supporting libraries
are also removed here.
