Dana Jansens 07aec169e1 Add min-preludes to more slow tests (#5681)
Adds min-preludes more tests which were seen as slow and their
surrounding neighbours. This drops the file_test runtime on my machine
from about 7s to about 6s.

For a few files that are clearly only testing diagnostics, we drop the
if-present semir ranges and the associated TODO.
