[dev.ssa] test: use SSA codegen for runnable tests

Browse Source 
Now that the standard library tests
are all passing, add the
test directory tests.

These contain a number of edge case tests
that are of particular interest for compilers.

Some kinds of tests are not well-suited
for a new backend, such as errorcheck tests.
To start, use SSA only for run and runoutput.

There are three failing tests now.
Just mark them as such for now,
so that we can prevent regressions.

This code will all be unwound once SSA
codegen matures and becomes the default.
