System-Level Testing

[biosbob]

a minimal set of automated tests applied prior to a new release of zigem

• ensure that all em.examples.* programs can compile
• use output from em.bench.coremark/ActiveRunnerP for regression
• regress program size using select examples
• use zigem compile --setup option to select between "default" and "sram" setups

ideally this should be invoked via zig build test; in the very near-term this can be implemented via shell scripts (or perhaps a standalone zig program).... maybe a zigem regress sub-command???

these tests could also be supplemented with some manual sanity tests -- such as running the combo example....
