Hexagon: Put relocations after instructions not packets.
Change relocation output so that relocation information follows individual instructions rather than clustering them at the end of packets. This change required shifting block of code but the actual change is in HexagonPrettyPrinter's PrintInst. Differential Revision: https://reviews.llvm.org/D46728 llvm-svn: 332283
