An x86 function returns a floating point value in st(0), and we must make sure it is popped, even if it is ununsed. A CopyFromReg node is too weak to represent the required sideeffect, so insert an FpGET_ST0 instruction directly instead. This will matter when CopyFromReg gets lowered to a generic COPY instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108037 91177308-0d34-0410-b5e6-96231b3b80d8
