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.
