[PATCH] D11438: Fix x86_64 fp128 calling convention

[Chih-Hung Hsieh via llvm-commits]

chh updated this revision to Diff 39757.
chh added a comment.

Use davidxl's suggestion and add case ISD::Register, CopyFromReg, CopyToReg into SoftenFloatResult. They are now only used when KeepFloat, to keep the node unchanged. All other not handled node opcode will still by default abort the compiler.
