re PR c/5972 (produces wrong assembly code when -march=pentiumpro and optimization...

	PR c/5972
	* config/i386/i386.md (movdicc_c_rex64, movsicc_noc, movhicc_noc,
	movsfcc_1, movdfcc_1): Add %O2.
	* config/i386/i386.c (print_operand): Handle %ON.
	Print . before float condition codes in Sun as cmov syntax.
	* config/i386/sol2.h (CMOV_SUN_AS_SYNTAX): Define for Sun as.
	* config.gcc (i[34567]86-*-solaris2*): Remove comment which is
	no longer true.
