r32900 introduced custom lowering for fcopysign, with two checks to change the magnitude value's type if it's larger/smaller than the sign value's type. r32932 replaced that code for the smaller case. r43205 did the same for the larger case, but left the old code, now dead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223415 91177308-0d34-0410-b5e6-96231b3b80d8
