Use pattern information to determine whether the use expects this instruction to produce a result. e.g MUL8m, the instruction does not produce a explicit result. However it produces an implicit result in AL which would be copied to a temp. The root operator of the matching pattern is a mul so the use would expect it to produce a result. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25458 91177308-0d34-0410-b5e6-96231b3b80d8
