I used this perl script to find unused _H macros in the Makefile.  I
deleted the definitions it reported and re-ran the script, until there
was no more output.

The script also makes note of _H variables which are used but never
defined.  That is how I found the TREE_GIMPLE_H use, fixed earlier in
the series.

Once Ada and the various config files are migrated to automatic
dependencies, we can run this script again and remove more things.
