This patch moves the DJB hash to support. This is consistent with other hashing algorithms living there. The hash is used by the DWARF accelerator tables. We're doing this now because the hashing function is needed by dsymutil and we don't want to link against libBinaryFormat. Differential revision: https://reviews.llvm.org/D42594 llvm-svn: 323616
