Mode-Switching: Fix SET_SRC ICE for create_pre_exit
In same cases, like gcc/testsuite/gcc.dg/pr78148.c in RISC-V, there will
be only 1 operand when SET_SRC in create_pre_exit. For example as below.
(insn 13 9 14 2 (clobber (reg/i:TI 10 a0)) "gcc/testsuite/gcc.dg/pr78148.c":24:1 -1
(expr_list:REG_UNUSED (reg/i:TI 10 a0)
(nil)))
Unfortunately, SET_SRC requires at least 2 operands and then Segment
Fault here. For SH4 part result in Segment Fault, it looks like only
valid when the return_copy_pat is load or something like that. Thus,
this patch try to fix it by restrict the SET insn for SET_SRC.
