This adds a regression test for https://crrev.com/c/2652488. The test
reduces the available code space such that it would trigger an OOM
condition if code is not garbage-collected.
In order to guarantee garbage-collection in all configurations, an
explicit interrupt check is added to the WasmDebugBreak runtime
function.
