add support for recursive phi translation and phi translation of add with immediate. This allows us to optimize this function: void test(int N, double* G) { long j; G[1] = 1; for (j = 1; j < N - 1; j++) G[j+1] = G[j] + G[j+1]; } to only do one load every iteration of the loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90013 91177308-0d34-0410-b5e6-96231b3b80d8
