[patch/rfc,6.1?] Use right frame ID in step_over_function

[Andrew Cagney]

Hello,

This goes into the "how did it ever work" category.  The idea of 
step_over_function is that it:

- finds the caller's resume address
- finds the caller's frame ID

and then sets a breakpoint for that caller instance of the function. 
The current code:

- finds the caller's resume address
- finds the _callee_ frame ID

and then uses that to set the breakpoint.  Now that is plain weird!  It 
only works because either:

- the step_frame_id patches up the bug

- the values match as GDB is using the inner-most, rather than 
outer-most frame address as part of the frame ID

The bug apepars when trying to step over nested shared library non-debug 
info functions (making sense?).

I'll follow this up after 6.1 branch is in place.

Its pretty heavy a change to apply to that branch and this late. 
However, like Joel's related patch, I suspect it will be needed :-/

Andrew
