This particular DAG combine is designed to kick in when both ConstantFPs will end up being loaded via a litpool, however those nodes have a semi-legal status, dictated by isFPImmLegal so in some cases there wouldn't have been a litpool in the first place. Don't try to be clever in those circumstances. Picked up while merging some AArch64 tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206365 91177308-0d34-0410-b5e6-96231b3b80d8
