[RFA] c++/11734

[Keith Seitz]

Hi,

c++/11734 involves being unable to set a breakpoint at a method defined 
in a different CU from the class declaration. This regression occurs 
because the dwarf2_physname patch removes the use of 
DW_AT_MIPS_linkage_name.

[You might ask why this is. I refer you to c++/11734 for a more detailed 
explanation of how gdb "appeared" to work prior to the dwarf2_physname 
patch.]

The attached patch fixes this regression. While testing, I also noticed 
a related issue with overloaded methods defined in multiple CUs, and 
I've fixed that, too.

Questions/comments/concerns?
