Subject: Begin adding experimental support for preserving use-list ordering of
 bitcode files.  First, add a new block USELIST_BLOCK to the bitcode format. 
 This is where USELIST_CODE_ENTRYs will be stored.  The format of the
 USELIST_CODE_ENTRYs have not yet been defined.  Add support in the
 BitcodeReader for parsing the USELIST_BLOCK. Part of rdar://9860654 and
 PR5680.
