This PR changes the counter-example accumulator in the match compiler
from
a `List` (built with cons, producing reverse order) to an `Array` (built
with push, preserving declaration order). Missing cases are now reported
in
the order constructors appear in the inductive type definition.
For example, given `inductive Enum | a | b | c | d`, missing cases `c`
and
`d` were previously shown as `d, c` and are now shown as `c, d`.

This PR sets up the new integrated test/bench suite. It then migrates
all benchmarks and some related tests to the new suite. There's also
some documentation and some linting.
For now, a lot of the old tests are left alone so this PR doesn't become
even larger than it already is. Eventually, all tests should be migrated
to the new suite though so there isn't a confusing mix of two systems.
