i386.md (*bt<mode>): Use nonimmediate_operand predicate for operand 1.

	* config/i386/i386.md (*bt<mode>): Use nonimmediate_operand
	predicate for operand 1.  Add (m,<S>) constraint.
	(*jcc_bt<mode>): Use nonimmediate_operand predicate for operand 1.
	Prevent memory operand 1 with register operand 2.
