	* config/tc-ia64.c (emit_one_bundle): Snapshot manual bundling state
	before actually using it. Don't generate an error in manual bundling
	mode when looking at an insn requiring slot 2 but not yet at slot 2.
	Don't generate an error in manual bundling mode when looking at an
	insn required to be last in its group but the required slot hasn't
	been reached, yet. Allow conversion from MII to MI;I for bundle
	consisting of only 2 insns with the stop between them. Suppress
	various meaningless errors resulting from detecting earlier ones.
