NAKAMURA Takumi 499befab31 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.
