[PATCH] D26168: Bitcode: Simplify BitstreamWriter::EnterBlockInfoBlock() interface.

pcc added a comment.

I am about to make `EnterBlockInfoBlock` more complicated in order to deal with multiple block info blocks, so I need all block info block writers to go through this function. The code width thing is just something I noticed in passing.
