After another three patches the entire function expand_tree_builtin
will be obsolete, and can be removed from C's build_function_call,
and C++'s build_cxx_call and build_function_call.  It will also
avoid the special casing of "fabs" in the Java front-end.

Its far easier for me to make all the necessary changes the the
middle-end (which I can approve for myself), and then propose a
single patch to eliminate "expand_tree_builtin" from c-common.c,
than to incrementally remove functionality from the C and C++
front-ends, requiring permission from the front-end maintainers
for each iteration.

This should clarify the "this is one of a series of patches" remark
in my original posting.
