Give base::SharedMemory::CreateAnonymous an executable flag
NaCl on Mac and Linux needs to create a shared memory object that it can
later make executable with mprotect. Express this need in the interface it
uses. Add a test that pages mapped from such an object can later be passed
to mprotect with PROT_EXEC.
This lays the groundwork for a later change that will sometimes use a
different method to allocate an object on Linux when it needs to be
executable. On some Linux distributions, shm_open yields objects whose
mappings cannot be made executable.
