Diego Novillo d8a2d370dc Factor unrelated declarations out of tree.h.
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.

Lawrence Crowl 9be0ac8c9e Finish conversion of uses of double_int to the new API.
Some old functionality required new interfaces, and these have been added to
double-int.[hc]:

  double_int::from_pair - static constructor function
  wide_mul_with_sign - double-wide multiply instruction
  sub_with_overflow - subtraction with overlow testing
  neg_with_overflow - negation with overlow testing
  divmod_with_overflow - div and mod with overlow testing

This patch corrects the bootstrap problem on HPPA, via the addition of
sub_with_overflow.  (The overflow properties of negation and addition are
different from subtraction.)

The prior two generations of the interface have been removed.

Some of these old interfaces are still used as static implementation in
double-int.c.

The changed compiler appears 0.321% faster with 80% confidence of being faster.

Tested on x86_64, HPPA, and SPARC.  However, there are changes to the avr
config files, and I have not tested those.
