* tree-optimize.c (init_tree_optimization_passes): Remove
pass_maybe_create_global_var.
* tree-pass.h (pass_maybe_create_global_var): Remove.
* tree-ssa-alias.c (aliases_computed_p): Declare.
(struct alias_info): Add field NUM_PURE_CONST_CALLS_FOUND.
(count_calls_and_maybe_create_global_var): Remove.
(pass_maybe_create_global_var): Remove.
(init_alias_info): Do not declare aliases_computed_p.
(maybe_create_global_var): If the function contains no
call-clobbered variables and a mix of pure/const and regular
function calls, create .GLOBAL_VAR.
Mark all call-clobbered variables for renaming.
(merge_pointed_to_info): Update comment.
(add_pointed_to_var): Likewise.
(is_escape_site): Likewise.
Accept struct alias_info * instead of size_t *.
Update all users.
Update AI->NUM_CALLS_FOUND and AI->NUM_PURE_CONST_CALLS_FOUND
as necessary.
* tree-ssa-operands.c (get_call_expr_operands): If
ALIASES_COMPUTED_P is false, do not add call-clobbering
operands.
* tree-ssa.c (init_tree_ssa): Set ALIASES_COMPUTED_P to false.
(delete_tree_ssa): Likewise.
