For example, when --fuzzing is off, %OptimizeFunctionOnNextCall now
crashes when given a non-function argument.

The following behaviors remain unchanged for now:
- %DeoptimizeFunction continues to do nothing if the function is not
  optimized.
- %DeoptimizeNow continues to do nothing if the top-most JS function
  is not optimized.
- %OptimizeOSR continues to do nothing if the function already has
  optimized code.

This changes the baseline of an inspector test setting breakpoints
within an asm.js module while the module is being executed. With the
validator it is not supported to switch from active WebAssembly code
back to debuggable interpreter code. Hence some previously expected
breakpoints no longer fire, the behavior is consistent across all
configurations now though.

In the asm.js to wasm pipeline, we generate an entry function with
BUILTIN code, but still attached to a TYPE_NORMAL script.
This fix avoids trying to set a breakpoint there, resulting in a crash
on DCHECK(shared->HasDebugInfo()).

Also add two inspector tests to track regressions.
