Using an LLVM IR aggregate return value type containing three or more integer values causes an abort in the fast isel pass. This patch adds two more registers to RetCC_PPC64_ELF_FIS to allow returning up to four integers with fast isel, just the same as is currently supported with regular isel (RetCC_PPC). This is needed for Swift and (possibly) other non-clang frontends. Fixes PR26190. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@272005 91177308-0d34-0410-b5e6-96231b3b80d8
