of the comparison.

	(cmpXf insns): Allow 0.0 for either operand of the
	comparison.  Update output template to handle 0.0 as one
	of the operands.
	(movsi insn, fp->fp case): Update constraints and template to
	allow store of zero into an FP register.
	(movhi insn, fp->fp case): Likewise.
	(movqi insn, fp->fp case): Likewise.
	(movdi insn, fp->fp case): Likewise.
	(movDF const_double pattern): Do not apply this pattern
	if the const_double is zero.
	(movdf insn, fp->fp and gr->gr cases): Update constraints
	and output template to allow store of zero into a FP or GR.
	Update condition string to allow zero as operand 1.
	(movsf insn, fp->fp and gr->gr cases): Likewise.  Also allow
	store of zero into a memory location.
