ARM: fix @llvm.convert.from.fp16 on softfloat targets.

We need to make sure we use the softened version of all appropriate operands in
the libcall, or things go horribly wrong. This may entail actually executing a
1-stage softening.

CodeGenPrep: fall back to MVT::Other if instruction's type isn't an EVT.

Should fix PR20474.
