+==================== Work084, patch #5:
+
+Add zero_extendditi2.  Improve lxvr*x code generation.
+
+This pattern adds zero_extendditi2 so that if we are extending DImode to
+TImode, and we want the result in a vector register, the compiler can
+generate MTVSRDDD.
+
+In addition the patterns for generating lxvr{b,h,w,d}x and stxvr{b,h,w,d}x
+were tuned to allow loading to gpr registers and storing from gpr
+registers.  This prevents needlessly doing direct moves to get the value
+into the vector registers if the gpr register was already selected.
