[PATCH] Kill cpp-id-data.h

[Nathan Sidwell <nathan at acm dot org>]

Now that cpp-id-data.h contains a single #include, we can kill it and 
have its includers simply point at the sub include.  That turns out to 
be a single file.

Except of course, the makefile & gty pieces that also need updates, but 
mechanical ones.

booted & tested on x86_64-linux, committing to trunk.
