* Makefile.in: Added rules for ipa-pure-const.c, ipa-reference.c,
ipa-reference.h, ipa-utils.c, ipa-utils.h, ipa-type-escape.c,
ipa-type-escape.h, tree-promote-statics.c
* ipa-pure-const.c, ipa-reference.c, ipa-reference.h, ipa-utils.c,
ipa-utils.h, ipa-type-escape.c, ipa-type-escape.h,
tree-promote-statics.c: new files.
* alias.c: (nonlocal_mentioned_p_1, nonlocal_mentioned_p,
nonlocal_referenced_p_1, nonlocal_referenced_p, nonlocal_set_p_1,
int nonlocal_set_p, mark_constant_function): Deleted.
(rest_of_handle_cfg): Removed call to mark_constant_function.
        (nonoverlapping_component_refs_p): Added calls to support
type based aliasing.
        * tree-ssa-alias.c (may_alias_p,
compute_flow_insensitive_aliasing): Ditto.
* calls.c (flags_from_decl_or_type): Removed reference to
cgraph_rtl_info.
(flags_from_decl_or_type): Support ECF_POINTER_NO_CAPTURE attribute.
* c-common.c (handle_pointer_no_capture_attribute): New function
and added pointer_no_capture attribute.
       * c-typeck.c (convert_arguments): Make builtins tolerant of having
too many arguments.  This is necessary for Spec 2000.
* cgraph.h (const_function, pure_function): Removed.
* common.opt: Added "fipa-pure-const", "fipa-reference",
"fipa-type-escape", and "ftree-promote-static".
* opts.c: Ditto.
* passes.c: Added ipa and tree-promote-statics passes.
* timevar.def: Added TV_IPA_PURE_CONST, TV_IPA_REFERENCE,
TV_IPA_TYPE_ESCAPE, and TV_PROMOTE_STATICS.
* tree.h: Support ECF_POINTER_NO_CAPTURE attribute.
* tree-dfa.c (referenced_var_lookup_if_exists): New function.
* tree-flow.h: Added exposed sra calls and addition of
reference_vars_info field for FUNCTION_DECLS.
* tree-pass.h: Added passes.
* tree-sra.c: (sra_init_cache): New function.
(sra_insert_before, sra_insert_after) Made public.
(type_can_be_decomposed_p): Renamed from type_can_be_decomposed_p
and made public.
* tree-ssa-alias.c (dump_alias_stats): Added stats for type based
aliasing. (may_alias_p): Added code to use type escape analysis to
improve alias sets.
* tree-ssa-operands.c (add_call_clobber_ops): Added parameter and
code to prune clobbers of static variables based on information
produced in ipa-reference pass.  Changed call clobbering so that
statics are not marked as clobbered if the call does not clobber
them.

* gcc.dg/tree-ssa/ssa-dce-2.c: Changed dg-options to run at -O2
since pure const detection cannot run at -O1 in c compiler.
* gcc.dg/tree-ssa/20030714-1.c Changed scanning patterns because we
can now optimize this case properly.
* gcc.dg/tree-ssa/sra-2.c: Changed to -O3 and removed xfail
because we now pass.
* gcc.dg/vect/vect-92.c: Removed out of bounds array access.
