[CIR][NFC] Reverse the polarity of RecordType complete/incomplete (llvm#1563)

This change reverse the polarity of the cir::RecordType incomplete
attribute, making the attribute name "complete" and reversing all checks
in the code accordingly. The asm layout still prints "incomplete" for
records that are not complete and treats the absence of this text as
meaning that the definition provided is complete.

No functional change is intended.
