Implement more aggressive folding of add operand lists when they contain multiplications of constants with add operations. This helps simplify several kinds of things; in particular it helps simplify expressions like ((-1 * (%a + %b)) + %a) to %b, as expressions like this often come up in loop trip count computations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73361 91177308-0d34-0410-b5e6-96231b3b80d8
