dearly: Emit DIEs for decls early in the compilation process.

This is the original patch from Michael Matz, ported to a more recent
mainline.

git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@214906 138bc75d-0d04-0410-961f-82ee72b054a4
Make gen_formal_parameter_die() merge DIEs from a previous execution.

Do not set DW_AT_inline incorrectly on all functions.

Do not remove formal parameters when a previous DIE has been found.
Instead, augment the missing bits later.

Make output_die() output the parent DIE for each DIE.
