Andreas Haas 7b138dd30d [wasm] Compile debug code lazily 
Currently V8 recompiles all functions of a WebAssembly module when a
debugging session starts. This is outdated behavior and
causes OOMs for developers. With this CL all compiled code just gets
removed when a debugging session starts, and debugging code gets
compiled lazily.

This behavior may lead to small delays whenever a new function gets
entered by the debugger. However, developers are used to debugging code
being slightly slower, and the small delays should be in the order of
few milliseconds. On the other hand, debug modules can be big,
sometimes even more than 1'000'000 functions, and developers reported
OOMs when debugging.
