    A llvm/test/Transforms/Inline/simplify-instruction-computeKnownFPClass-context.ll

  Log Message:
  -----------
  ValueTracking: Check instruction is in a parent in computeKnownFPClass

For some reason the inliner calls simplifyInstruction with disembodied
instructions. I consider this to be an API defect. Either the instruction
should always be inserted prior to simplification, or we at least
should pass in the new function for the context.
