vecir.h: New file with VEC primitives for tree, gimple, and rtl.
gcc/ChangeLog
* vecir.h: New file with VEC primitives for tree, gimple, and rtl.
* Makefile.in: Add it.
Fix all other Makefile dependencies for changes below.
* tree.h: Include it instead of defining VEC primitives here.
* gimple.h: Likewise.
* rtl.h: Likewise.
* tree-inline.h: Inlclude vecir.h instead of gimple.h.
* except.h: Include vecir.h, break dependence on tree.h.
* gimplify.c (append_to_statement_list_1, append_to_statement_list):
Move from here...
* tree-iterator.c: ...to here.
* tree-iterator.h: Fix file introduction comment. Add extern markers.
* c-lex.c: Include fixed-value.h instead of rtl.h. Do not include
tm_p.h.
* c-cppbuiltin.c: Explain why debug.h and tm_p.h are included.
* c-objc-common.h: Do not include tm.h, rtl.h, insn-config.h,
integrate.h, function.h, toplev.h, tree-inline.h, ggc.h,
tree-mudflap.h, and target.h.
* c-semantics.c: Do not include except.h, ggc.h, rtl.h, timevar.h,
predict.h, tree-inline.h, gimple.h, and langhooks.h.
* c-decl.c: Do not include expr.h, ggc.h, libfuncs.h, except.h.
Add FIXME for why gimple.h is still included (should be unnecessary
since GCC 4.5 gimplification unit-at-a-time).
* c-typeck.c: Do not include rtl.h, tm_p.h, ggc.h, and gimple.h.
* c-pragma.c: Add FIXME for why function.h needs to be included just
for cfun, at front-end level.
Add note that REGISTER_TARGET_PRAGMAS should probably be a target hook.
Do not include ggc.h, but include vecprim.h for VEC(char).
* c-opts.c: Do not include tm.h, tree-inline.h, and tm_p.h.
Explain why target.h is included.
* c-omp.h: Do not include tm.h, function.h, and bitmap.h.
Explain why gimple.h is included.
* c-ppoutput.c: Do not include tm.h.
* c-common.c: Do not include gimple.h. Explain why expr.h is included.
* c-parses.c: Explain why rtl.h is included, and that this (and only
this) is also why tm.h must be included.
Do not include except.h.
* c-lang.c: Do not include ggc.h.
cp/ChangeLog
* decl.c: Include tree-iterator.h, as fixup for tree-inline.h changes.
* Make-lang.in: Fix dependencies accordingly.

backport: Makefile.in (TREE_INLINE_H): New.
Merge from gomp branch:
* Makefile.in (TREE_INLINE_H): New. Use it as needed.
* tree-inline.h (struct copy_body_data): Move from tree-inline.c
and rename from struct inline_data. Rename callee* to dst*;
caller* to src*; add copy_decl hook, transform_call_graph_edges,
transform_new_cfg, transform_return_to_modify, and
transform_lang_insert_block flags; remove cloning_p, versioning_p,
update_clones_p.
(copy_body_r, insert_decl_map, remap_decl, remap_type): Declare.
(copy_decl_for_dup): Remove.
* tree-inline.c (struct inline_data): Move to header.
(insert_decl_map): Export.
(remap_decl): Update for member name changes. Use copy_decl hook.
Allow for replacement to be a non-decl. Remove dead code.
(remap_type_1): Check for existing mapping.
(remap_type): Export.
(remap_decls): Update for member name changes.
(remap_block, copy_bb, copy_cfg_body, copy_generic_body): Likewise.
(copy_body, setup_one_parameter, declare_return_variable): Likewise.
(expand_call_inline, optimize_inline_calls, clone_body): Likewise.
(copy_tree_r, mark_local_for_remap_r, unsave_expr_now): Likewise.
(tree_function_versioning, build_duplicate_type): Likewise.
(copy_body_r): Likewise. Export.
(copy_decl_for_dup): Split into ...
(copy_decl_for_dup_finish, copy_decl_to_var,
copy_decl_no_change, copy_decl_maybe_to_var): ... these.
(replace_ref_tree, inlining_p): Remove.
