* tree-ssa-dse.c (get_use_of_stmt_lhs): Give up on uses
with calls.

* tree-ssa-dse.c (aggregate_vardecl_d): New.
(dse_global_data): Add aggregate_vardecl field.
(dse_possible_dead_store_p): New.
Add prev_defvar variable.
Allow immediate uses and previous immediate uses to differ
if they are setting different parts of the whole.
(get_aggregate_vardecl): New.
(dse_record_partial_aggregate_store): New.
(dse_whole_aggregate_clobbered_p): New.
(dse_partial_kill_p): New.
Call dse_maybe_record_aggregate_store().
When checking whether a STMT and its USE_STMT refer to the
same memory address, check also for partial kills that clobber
the whole.
Move some variable definitions to the block where they are used.
(aggregate_vardecl_hash): New.
(aggregate_vardecl_eq): New.
(aggregate_vardecl_free): New.
(aggregate_whole_store_p): New.
(tree_ssa_dse): Initialize and free aggregate_vardecl.
Mark which aggregate stores we care about.
