These tests unnecessarily rely on the `//# sourceURL` annotation. This
is preparatory work to eventually move the treatment of `sourceURL` to
the DevTools front-end.

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.

All wasm code has an initial ref count of 1, in the expectation that it
will be added to the code table. When the code is removed from that
table, the ref count will be decremented.
Stepping code (and also other code under special circumstances) will not
be added to the code table though. Hence the ref count will never be
decremented below 1, and the code will never be garbage-collected.
This CL fixes this, by decrementing the ref count if the code is not
added to the code table.
Note that the code will only be collected if no isolate is currently
using it, so it won't be collected while still in use for stepping.
