* config/tc-i386.c (intel_e09_1): Only flag as a memory operand if
	it's not an offset expression.
	(intel_e10_1): Ditto. Also, if the operand is an offset expression,
	keep the braces '[' and ']' in the output string.
	(intel_e11): Ditto. Also remove comparison intel_parser.op_modifier
	!= FLAT. There is no such op_modifier.
