* cgraph.h (cgraph_indirect_call_info): New field thunk_delta.
* gimple.h (gimple_fold_obj_type_ref): Declaration removed.
(gimple_fold_call): Declare.
(gimple_adjust_this_by_delta): Likewise.
* cgraph.c (cgraph_make_edge_direct): New parameter delta. Updated
all users.
(cgraph_clone_edge): Create a copy of indirect_info also for direct
edges.
* cgraphunit.c (cgraph_redirect_edge_call_stmt_to_callee): Adjust this
parameters.
* gimple-fold.c (gimple_fold_obj_type_ref_known_binfo): Renamed to
gimple_get_virt_mehtod_for_binfo, new parameter delta. Do not search
through thunks, in fact bail out if we encounter one, check that
BINFO_VIRTUALS is not NULL.
(gimple_adjust_this_by_delta): New function.
(gimple_fold_obj_type_ref): Removed.
(gimple_fold_obj_type_ref_call): New function.
(fold_gimple_call): Renamed to gimple_fold_call, made external.
Updated users. Call gimple_fold_obj_type_ref_call instead of
gimple_fold_obj_type_ref.
* ipa-cp.c (ipcp_process_devirtualization_opportunities): Process
thunk deltas.
(ipcp_discover_new_direct_edges): Likewise.
* ipa-prop.c (ipa_make_edge_direct_to_target): New parameter delta.
Updated callers.
(ipa_write_indirect_edge_info): Stream thunk_delta.
(ipa_read_indirect_edge_info): Likewise.
* tree-ssa-ccp.c (ccp_fold_stmt): Use gimple_fold_call instead of
gimple_fold_obj_type_ref.
* testsuite/g++.dg/ipa/pr46053.C: New test.
* testsuite/g++.dg/ipa/pr46287-1.C: Likewise.
