i386.md (float_truncate splitter, [...]): Add reload_completted; fix operand predicate.

Browse Source 
* i386.md (float_truncate splitter, and to mov splitters): Add
	reload_completted; fix operand predicate.

	* haifa-sched.c (sched_init): Do not split insns.
	* toplev.c (rest_of_compilation): Call split_all_insns before
	sched1 pass; simplify condition of post-reload splitter;
	call split_all_insn before sched2 pass.
