* cgraph.h (cgraph_local_info): New field can_change_signature.
* ipa-cp.c (ipcp_update_callgraph): Only compute args_to_skip if callee
signature can change.
(ipcp_estimate_growth): Call sequence simplify only if calle signature
can change.
(ipcp_insert_stage): Only compute args_to_skip if signature can change.
(cgraph_function_versioning): We can not change signature of functions
that don't allow that.
* lto-cgraph.c (lto_output_node): Stream local.can_change_signature.
(lto_input_node): Likewise.
* ipa-inline.c (compute_inline_parameters): Compute
local.can_change_signature.
* ipa-split.c (visit_bb): Never split away APPLY_ARGS.
* tree-sra.c (ipa_sra_preliminary_function_checks): Give up on functions
that can not change signature.
* i386.c (ix86_function_regparm, ix86_function_sseregparm,
init_cumulative_args): Do not use local calling conventions for functions
that can not change signature.

I've commited patch fixing the testcase. H.J., can you please confirm that the
LTO 32bit faiulres are gone for you?
