Subject: [RFA] Implement DW_TAG_*_parameter_pack

Hello,

The patch adding support for template parameters debug info (PR
debug/30161) used a naive trick to represent parameter packs:
http://gcc.gnu.org/wiki/TemplateParmsDwarf .

It appeared that a better proposal was submitted to the DWARF committee for
that very same purpose:
http://wiki.dwarfstd.org/index.php?title=C%2B%2B0x:_Variadic_templates

This attached patch modifies what was done for PR debug/30161 to implement
the proposal linked above.
The PR it refers to is just a bugzilla enhancement request I filled to
track this task.

Bootstrapped and tested against trunk on x86_64-unknown-linux-gnu.

Comments ?

Thanks.
