* tree.c (tree_size): For all 'c' and 'x' nodes, look directly
at the sizes of the relevant structures, rather than relying
on TREE_CODE_LENGTH. Call lang_hooks.tree_size to get the
sizes of any such we don't know about. Use
lang_hooks.identifier_size for IDENTIFIER_NODE.
(initializer_zerop): Use CONSTRUCTOR_ELTS.
* tree.def: Update commentary. Make fourth element of
the definition for all 'c' and 'x' nodes zero.
* langhooks.h: New hook, tree_size / LANG_HOOKS_TREE_SIZE.
* langhooks-def.h: Update to match.
* langhooks.c: New default, lhd_tree_size.
* c-common.def (SRCLOC): Kill.
* c-pretty-print.c (pp_c_postfix_expression [case SRCLOC]):
Remove entirely - was already #if-ed out.
ada:
* ada-tree.def: Make fourth element for GNAT_LOOP_ID zero.
* misc.c (gnat_tree_size): New function.
(LANG_HOOKS_TREE_SIZE): Override.
cp:
* cp-tree.def: Make fourth element for all 'c' and 'x' nodes zero.
* cp-lang.c (cp_tree_size): New function.
(LANG_HOOKS_TREE_SIZE): Override.
* cp-tree.h (SOURCE_LOCUS, SRCLOC_FILE, SRCLOC_LINE, struct
tree_srcloc, TS_CP_COMMON, TS_CP_SRCLOC): Kill.
(union lang_tree_node): Remove common and srcloc members.
(build_srcloc_here): Don't prototype.
* decl.c (cp_tree_node_structure): Kill SRCLOC case.
* pt.c (pending_templates): Correct comment.
* tree.c (build_srcloc, build_srcloc_here): Kill.

* stmt.c (all_cases_count): Set lastval to thisval at end of loop.
Rename spareness variable to sparseness.
(expand_end_case_type): Renamed from expand_end_case, use orig_type
if non-NULL instead of TREE_TYPE (orig_index).

(expand_end_case): Define using expand_end_case_type.
* c-semantics.c (genrtl_switch_stmt): Pass SWITCH_TYPE
to expand_end_case_type.
* doc/c-tree.texi (SWITCH_STMT): Document SWITCH_TYPE.
* semantics.c (begin_switch_stmt): Clear SWITCH_TYPE.
(finish_switch_cond): Set SWITCH_TYPE.
