Manual tweak of some end_sequence callers

This patch mops up obvious redundancies that weren't caught by the
automatic regexp replacements in earlier patches.  It doesn't do
anything with genemit.cc, since that will be part of a later series.

gcc/
	* config/arm/arm.cc (arm_gen_load_multiple_1): Simplify use of
	end_sequence.
	(arm_gen_store_multiple_1): Likewise.
	* expr.cc (gen_move_insn): Likewise.
	* gentarget-def.cc (main): Likewise.
