functions (scalar, aggregate and member pointer).
(ipa_get_member_ptr_load_param): Incorporate into
ipa_get_stmt_member_ptr_load_param, also pass back an offset.
(ipa_note_param_call): Clear agg_contents.
(ipa_analyze_indirect_call_uses): Also look for simple pointers loaded
from aggregates. In such cases, store offset of the called field.
(ipa_analyze_node): Initialize new fields of param_analysis_info.
(update_jump_functions_after_inlining): Handle aggregate contents.
(ipa_find_agg_cst_for_param): New function.
(try_make_edge_direct_simple_call): Handle called aggregate values.
(update_indirect_edges_after_inlining): Make sure aggregate preserving
jump functions comply with type compatibility requirements.
(ipa_edge_duplication_hook): Copy also aggregate jump functions.
(ipa_write_jump_function): Stream agg_preserved flags and aggregate
jump functions. Do not stream member pointer constant jump functions.
(ipa_read_jump_function): Likewise.
(ipa_write_indirect_edge_info): Stream new cgraph_indirect_call_info
fields.
