all: fail faster on dirty working tree

It's annoying to get through all the tests for five different language
versions to discover at the end that you've got an uncommitted file
sitting around in your working tree, or you forgot to run
regenerate.bash.

Report uncommitted changes at the start of tests (so you can ^C and
fix the problem right off if you didn't know about it), but hold off on
failing the test until the end so you can still run tests on uncommitted
changes.

Fail immediately if generated files are out of date.
