Enhance address-mode folding of ISD::ADD to handle cases where the operands can't both be fully folded at the same time. For example, in the included testcase, a global variable is being added with an add of two values. The global variable wants RIP-relative addressing, so it can't share the address with another base register, but it's still possible to fold the initial add. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66865 91177308-0d34-0410-b5e6-96231b3b80d8
