This is mostly a copy of the existing FastISel GEP code, but we have to duplicate it for AArch64, because otherwise we would bail out even for simple cases. This is because the standard fastEmit functions don't cover MUL at all and ADD is lowered very inefficientily. The original commit had a bug in the add emit logic, which has been fixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@219831 91177308-0d34-0410-b5e6-96231b3b80d8
