From-SVN: r205863

This patch applies the rule that functions defined in FOO.c must be
declared in FOO.h. One of the worst offenders in the code base is
tree.h, unsurprisingly.

The patch creates several new headers: attribs.h calls.h fold-const.h
gcc-symtab.h print-rtl.h print-tree.h stmt.h stor-layout.h stringpool.h
tree-nested.h tree-object-size.h varasm.h.

Functions in each corresponding .c file got moved to those headers and
others that already existed. I wanted to make this patch as mechanical
as possible, so I made no attempt to fix problems like having
build_addr defined in tree-inline.c. I left that for later.

There were some declarations that I could not move out of tree.h
because of header poisoning or the use of target macros. We forbid the
inclusion of things like expr.h from FE files. While that's a
reasonable idea, the FE file *still* manage to at expr.c functionality
because the declarations they want to use were defined in tree.h.

The affected files are builtins.h, emit-rtl.h and expr.h.

If that functionality is allowed to be accessed from the FEs,
then I will later move those functions out of expr.c into tree.c.
I have moved these declarations to the bottom of tree.h so they
are easy to identify later.

There is a namespace collision with libcpp. The file gcc/symtab.c
cannot use gcc/symtab.h because the #include command picks up
libcpp/include/symtab.h first. So I named this file gcc-symtab.h
for now.

Finally, I added a new header to PLUGIN_HEADERS to account for the
tree.h refactoring. I did not add all headers factored out of tree.h
because it is unclear (and impossible to tell) what plugins need.
This adds the one header used by the plugins in the testsuite.

This will be changing quite dramatically as we progress with the header
refactoring.

This patch should offer some minimal incremental build advantages
by reducing the size of tree.h. Changes that would otherwise
affected tree.h, will now go to other headers which are less
frequently included.

This patch rewrites the old VEC macro-based interface into a new one based on the template class 'vec'.

This patch rewrites the old VEC macro-based interface into a new one
based on the template class 'vec'.  The user-visible changes are
described in http://gcc.gnu.org/wiki/cxx-conversion/cxx-vec.

I have tested the patch pretty extensively:

- Regular bootstraps on x86_64, ppc, ia64, sparc and hppa.
- Bootstraps with --enable-checking=release
- Bootstraps with --enable-checking=gc,gcac
- Basic builds on all targets (using contrib/config-list.mk).

We no longer access the vectors via VEC_* macros.  The pattern is
"VEC_operation (T, A, V, args)" becomes "V.operation (args)".

The only thing I could not do is create proper ctors and dtors for the
vec class.  Since these vectors are stored in unions, we
have to keep them as PODs (C++03 does not allow non-PODs in unions).

This means that creation and destruction must be explicit.  There is a
new method vec<type, allocation, layout>::create() and another vec<type,
allocation, layout>::destroy() to allocate the internal vector.

For vectors that must be pointers, there is a family of free functions
that implement the operations that need to tolerate NULL vectors.
These functions all start with the prefix 'vec_safe_'.  See the wiki
page for details.

The gengtype change removes the special handling for VEC() that used
to exist in gengtype. Additionally, it allows gengtype to recognize
templates of more than one argument and introduces the concept of an
undefined type (useful for template arguments that may or may not be
types).

When a TYPE_UNDEFINED is reached, gengtype will ignore it if it
happens inside a type marked with GTY((user)).  Otherwise, it will
emit an error.

Finally, gengtype rejects root types marked GTY((user)) that are not
first class pointers.
