   MULT into an ASHIFT which in turn allows postreload-gcse to
   find the common subexpression.

   Neither pass dumps stuff in a format that is particularly good
   for parsing here, so we count the shadd insns.  More is not
   necessarily better in this test.  If this test is too fragile
   over time we'll have to revisit the combine and/or postreload
   dumps.  Note we have disabled delay slot filling to improve
   test stability.  */
