	* reorg.c (mark_referenced_resources): Parameter include_called_routine
	changed to include_delayed_effects.  All references changed.
	(mark_set_resources): Likewise.
	(insn_references_resource_p): Likewise.
	(insn_sets_resource_p): Likewise.
	(mark_referenced_resources, case INSN): Do not mark any resources
	as referenced if we are not including delayed effects, and the
	given insn has delayed effects.
	(mark_set_resources): Likewise for resources which are set/clobbered.
	(fill_simple_delay_slots): Include delayed effects for the delay insn
	if we are searching after the delay insn for candiates.
	(dbr_schedule): When initializing `end_of_function_needs' include
	delayed effects.

	occuring in millicode insns.

(get_inner_reference): Simplify code by initializing OFFSET to

Do general index computation for ARRAY_REF and include lower bound of domain

Use MIN when helpful.
Be consistent and don't test cost before recursive call.
Don't special-case shift counts of zero; already handled elsewhere.
(expand_mult): First operation is always alg_zero or alg_m; remaining
operations can't be one of those.
Use proper subtargets for computations.
Remove special-cases for shift counts of zero.

(expand_float): When converting an unsigned type U
to a smaller or equal-sized floating type F where there's no
hardware support for unsigned-to-float conversion, use a temporary
floating type larger than F if possible, since this avoids
rounding problems that are worst when U is just greater than
the maximum signed integer of the same size.
