The tied source operand of tMUL is the second source operand, not the first like every other two-address thumb instruction. Special case it in the size reduction pass to make sure we create the tMUL instruction properly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151315 91177308-0d34-0410-b5e6-96231b3b80d8
