that doesn't cut it. callers of tsubst_qualified_id expect a non-dependent
expression back (because they feed it to things like build_x_binary_op).
And, in this case processing_template_decl will be false, so it all breaks.

This patch increments processing_template_decl when we're tsubsting
an incomplete explict arg list.

booted & tested on i686-pc-linux-gnu, ok?
