Jim will need to ok this. A few concerns follow. Most of the time when we don't 
get the DWARF -> AST conversion right, it can mean that we might code gen 
incorrect code. Is there not enough information for the GNU abi_tag in the 
DWARF to actually re-create these classes correctly in the AST? My first 
inclination would be to fix that if possible. If there is info missing from the 
DWARF such that we can't re-create the AST correctly, then it seems that this 
approach will help. Can you clarify what the GNU abi_tag stuff does? Will it 
change how code would be generated? If we have things in the AST that aren't 
correct, but have been fixed by correcting the "asm" tag, will we JIT up bad 
code?
