* dse.c (find_shift_sequence): Reinstate "<= UNITS_PER_WORD" condition.
* var-tracking.c (micro_operation_def): Update comment on u.loc.
(mode_for_reg_attrs, var_lowpart): New functions.
(add_uses): Consider recording a lowpart of LOC for MO_USE.
(add_stores): Likewise MO_SET and MO_COPY. If the source of a set
or copy is known, set LOC to the SET that performs the set, instead
of the destination.
(find_src_status, find_src_set_src): Remove LOC parameter.
Replace INSN with the source value.
(compute_bb_dataflow, emit_notes_in_bb): Check for a SET u.loc when
handling MO_SET and MO_COPY. Update the calls to find_src_status
and find_src_set_src.
