The patch simply keeps/uses MIPS_linkage_name for Ada. Almost nothing 
else is changed. I've attached it. With this patch, Ada tests now fail 
as much as they did before. I'm guessing there is a lot more to do, though.

It is incomplete in the fact that I did not spend much time with it, and 
this patch is quite hacky. If we want to incorporate something like 
this, I'll need to play with it a bit first. Probably want to try to 
move this from dwarf2_name to dwarf2_physname, if that's even possible. 
[DW_AT_name and DW_AT_MIPS_linkage_name don't appear to be related in 
any way in the test cases I've seen.]
