      [wasm][debug] Implement instrumentation breakpoints · 15f3392a
      Clemens Backes authored
      This CL adds support for instrumentation breakpoints in wasm. The
      request for "break on entry" is set on the script, and we need to keep
      it stored there because there might not be any instances of that wasm
      module yet. Once instances get created, the flag value is transferred to
      all instances. The flag stored there is then checked in the function
      prologue in Liftoff debugging code. This ensures that we will stop at
      the first valid break position in any function within that module.
      Hitting that instrumentation breakpoint will then clear the flag from
      the script and from all other live instances (in the same isolate).
      
      A first basic test is contained in this CL. More tests will be added
      later.
