sh.c (calc_live_regs): Multiply value assigned to *COUNT_PTR by UNITS_PER_WORD.
* sh.c (calc_live_regs): Multiply value assigned to *COUNT_PTR by
UNITS_PER_WORD. Change caller initial_elimination_offset.
(rounded_frame_size): Take into account that argument pushed has
changed. Fix TARGET_ALIGN_DOUBLE problem.
