mips.md: Add imadd type.

	* config/mips/mips.md: Add imadd type.  Update scheduler description
	to use imadd as well as imul.
	(*mul_acc_si, *madsi): Change imul alternatives to imadd.
	(*mul_acc_di, *mul_acc_64bit_di): Likewise.
	(*mul_sub_si): Likewise for first alternative.  Change second
	alternative from imul to multi.
