Bisection has identified this change:

* dse.c (find_shift_sequence): Allow word as well as subword shifts.
Do the tentative shift expansion with the DF_NO_INSN_RESCAN flag set.
Fix the call to insn_rtx_cost. Skip access sizes that require a
real truncation of the store register. Use convert_move instead
of gen_lowpart when narrowing the result.
(replace_read): Use convert_move instead of gen_lowpart when
narrowing the store rhs.
