[Dwarf-Discuss] C++11 local types as template arguments

The C++11 standard allows types with no linkage such as function-local
classes to be used as template arguments. This complicates partitioning
function debug info into a separate compilation unit, as nothing else
would require a symbolic reference into the function info. To avoid
this, I want to leave the type info out of the function unit, but it
will need a function skeleton to live in for proper scoping.
One solution to this would be to force an abstract/complete split for
affected functions even if they are not inline. But not everything in
the abstract function needs to move out of the function unit; it would
be nice if I could just move the type to a function declaration in the
main CU. I can't seem to find a rule against this, does it seem
reasonable to other people?
