Add min-preludes to most of lowering and a few more slow tests (#5680)

Adds min-preludes to a few more slowest tests, and adds them to most of
the lowering tests, with a few exceptions that make use of operators.
This take the runtime of file_test down from about 8s to about 7s on my
machine.

We add support for Negate on uints in the min-preludes.
