- Fix using CreateCoercedStore for promoted float parameters.

For promoted parameters double -> float conversion should use fptrunc, not
casting through memory preserving bits. Tried to change CreateCoercedStore to
do CreateFPCast but it caused CodeGen/arm-fp16-arguments.c to fail as it
expects __fp16 values to be passed in the least-significant 16 bits.
