[PATCH] ia64 segfault on nop in X-slot of MLX bundle

["Jan Beulich" <JBeulich at novell dot com>]

Using the nop alias insn as the second one in an MLX bundle caused the
assembler to segfault; the Intel assembler accepts this.

Built and tested on ia64-unknown-linux-gnu.

	* config/tc-ia64.c (emit_one_bundle): Allow .x suffix when
resolving
	dynamic insns.
