PR tree-optimization/18587
* tree-flow-inline.h (mark_call_clobbered, mark_non_addressable): Flag
call clobbered caches as invalid.
* tree-ssa-operands.c (ssa_call_clobbered_cache_valid): New. Flag
indicating whether the call clobbered operand cache is valid.
(ssa_ro_call_cache_valid): New. Flag indicating whether the pure/const
call operand cache is valid.
(clobbered_v_may_defs, clobbered_vuses, ro_call_vuses): New.
cached list of operands for cached call virtual operands.
(clobbered_aliased_loads, clobbered_aliased_stores,
ro_call_aliased_load): New. flags caching whether alias bits are to be
set in call stmt's. */
(fini_ssa_operands): Remove call operand caches if present.
(get_expr_operands, get_asm_expr_operands, get_indirect_ref_operands):
Pass stmt annotation to add_stmt_operand.
(get_call_expr_operands): Add call clobbered variables first.
(add_stmt_operand): Take stmt annotation rather than stmt as a param.
(add_call_clobber_ops, add_call_read_ops): Use the call operand cache
if it is valid, otherise fill the cache.
* tree-ssa-operands.h (ssa_clobbered_cache_valid): Declare extern.
* tree-flow.h (struct var_ann_d): Add in_vuse_list and in_v_may_def_list
bits.
* tree-ssa-operands.c (cleanup_v_may_defs): New. Clear the in_list bits
for the v_may_def elements and empty the operand build array.
(finalize_ssa_vuses): Use cleanup_v_may_defs and remove redundant VUSES
by checking the in_v_may_def_list bit.
(append_v_may_def, append_vuse): Use the in_list bit rather than
scanning the array for duplicates.
