[Alignment] fix dubious min function alignment

Browse Source 
Summary:
This was discovered while introducing the llvm::Align type.
The original setMinFunctionAlignment used to take alignment as log2, looking at the comment it seems like instructions are to be 2-bytes aligned and not 4-bytes aligned.
