The definition of the MemInfoBlock is shared between the memprof compiler-rt runtime and llvm/lib/ProfileData/. This change removes the memprof_meminfoblock header and moves the struct to the shared include file. To enable this sharing, the Print method is moved to the memprof_allocator (the only place it is used) and the remaining uses are updated to refer to the MemInfoBlock defined in the MemProfData.inc file. Also a couple of other minor changes which improve usability of the types in MemProfData.inc. * Update the PACKED macro to handle commas. * Add constructors and equality operators. * Don't initialize the buildid field.
