[PATCH] Step over Objective-C dispatch function

[Andrew Cagney]

Just on the coding side (let michael handle the technical bit :-).  That 
file contains the nastiest code known to GDB so all possible effort 
should be spent on ensuring that the new code is understandable.

>    CORE_ADDR tmp;

Hmm, looks like the variable tmp needs a re-name, it's definitly no 
longer tmp - it's carrying a meaningful value.

>> +  CORE_ADDR new_stop;

this declaration should be moved as close as possible to its use (and 
again given a descriptive name).

 > +      /* Step over Objective-C dispatch function.  */

Following on from michael's comment, this needs a detailed description 
of what is happening here.
