[PATCH] D84417: [MSP430] Do not use __mspabi_cmp[fd] for FP comparisons

[Anatoly Trosinenko via Phabricator via llvm-commits]

Hmm, this probably needs further investigations... On one hand, condition codes such as `ISD::SETNE` are explicit "Don't care operations: undefined if the input is a nan" - that is, exactly how the `__mspabi_cmp[fd]` are described in MSP430 EABI document. On the other hand, how a fully fledged comparison libcall can be specified then?
