PATCH: break lines in announce_function

- Subject: PATCH: break lines in announce_function
Hello All,
When running cc1 in verbose mode, the announce_function from gcc/toplevel.c
displays the name of the function. However, it never emits any newline
characters. As a result, the stderr stream may contains very long lines,
which is visually unpleasant and tend to block Emacs when running cc1 -v
inside an Emacs buffer (or agdb session inside Emacs).
The attached patch (backbported from the MELT branch, where it is very
useful) fixes this issue by adding a newline once every eight identifiers.

* toplev.c (announce_function): Emit newline periodically.
