re PR target/70110 (ICE at -O3 in the 32-bit mode in set_last_insn, at emit-rtl.h:420) 

PR target/70110
	* config/i386/i386.c (scalar_chain::make_vector_copies,
	scalar_chain::convert_reg): Call end_sequence in between
	get_insns and emit_conversion_insns rather than after both
	calls.

	* gcc.dg/pr70110.c: New test.
