Richard Sandiford 385399a875 Split up optabs.[hc] 
optabs.[hc] is a bit of a behemoth.  It includes basic functions for querying
what a target can do, related tree- and gimple-level query functions,
related rtl-level query functions, and the functions that actually
generate code.  Some gimple optimisations therefore need:

#include "insn-config.h"
#include "expmed.h"
#include "dojump.h"
#include "explow.h"
#include "emit-rtl.h"
#include "varasm.h"
#include "stmt.h"
#include "expr.h"

purely to query whether the target has support for a particular operation.

This patch splits optabs up as follows:

      - optabs-query.[hc]: IL-independent functions for querying what a target
          can do natively.
      - optabs-tree.[hc]: tree and gimple query functions (an extension of
          optabs-query.[hc]).
      - optabs-libfuncs.[hc]: optabs-specific libfuncs (an extension of
          libfuncs.h)
      - optabs.h: For now includes optabs-query.h and optabs-libfuncs.h.

Only two files outside optabs need to include both optabs.h and
optabs-tree.h: expr.c and function.c.  I think that's expected given
that both are related to expand.

It might be good to split optabs.h further, but this is already quite
a big patch.

I changed can_conditionally_move_p from returning an int to returning
a bool and fixed a few formatting glitches.  There should be no other
changes to the functions themselves.

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.

Richard Henderson 22e4dee74f Change vec_perm checking and expansion level. 
The can_vec_perm_p interface changed to use a C integer array.  This
allows easy re-use from the rtl level and the gimple level within
the vectorizer.  It allows both to determine if a given permutation
is (un-)supported without having to create tree/rtl garbage.

The expand_vec_perm interface changed to use rtl.  This allows easy
re-use from the rtl level, so that expand_vec_perm can be used in the
fallback implementation of other optabs.
