MemoryBuffer: Don't use mmap when FileSize is multiple of 4k on Cygwin.
On Cygwin, getpagesize() returns 64k(AllocationGranularity). In r214580, the size of X86GenInstrInfo.inc became 1499136. FIXME: We should reorganize again getPageSize() on Win32. MapFile allocates address along AllocationGranularity but view is mapped by physical page. llvm-svn: 214681
