getters_setters2_test needs triage

[MichaelRFairhurst]

This is not an effective test right now for the analyzer:

class T2 {                                                                       
  A getterField;                                                                 
  C setterField;                                                                 
  A get field {                                                                  
    return getterField;                                                          
  }                                                                              
                                                                                 
  // Type C is not assignable to A                                               
  void set field(C arg) { setterField = arg; } //# 01: static type warning       
}

We actually get an error on A get field. This means our status file is:

getters_setters2_test/01: CompileTimeError 

because A get field only fails on test case 01, and CompileTimeError supercedes MissingCompileTimeError?

But this is not a good test of the actual issue.

Maybe its as simple as moving the //# 01 case up to A get field, but I'm filing an issue because test changes are so tedious.

Note also #34349 which makes this error a warning (along with several others).

This CL adjusts dartLangSpec.tex such that the compile-time error mentioned above is changed to a warning.
