Test case for Blackfin back-end

The attached test case fails with

Assertion failed: (LC != RTLIB::UNKNOWN_LIBCALL && "Unsupported FP_TO_SINT!"),
function SoftenFloatOp_FP_TO_SINT, file
/Users/stoklund/llvm/lib/CodeGen/SelectionDAG/LegalizeFloatTypes.cpp, line 693.

I believe this happens when using soft-float on any target with legal i8 or i16
types:

llc -march=x86 -soft-float
llc -march=x86-64 -soft-float
llc -march=pic16
llc -march=bfin
llc -march=msp430
