Clemens Backes 447d7d6784 [wasm][debug] Avoid repeated recompilation 
If multiple isolates share the same module, and the debugger gets
enabled, then we trigger tier down in each isolate separately. To avoid
generating too much code, we only recompile functions that are not
already in the right tier.

This CL is only the first step towards an actual fix. Since we only
check already installed code (and ignore compilations that are already
scheduled), we might still compile the same functions multiple times. A
second CL will make sure that only one recompilation is running at the
same time.
