just tag them with a fixnum constant.

VM: put the singletons t, -1, 0 and 1 in the special objects table

Having them there instead of as fields in the vm struct removes a bunch

old ones to avoid potential chicken-and-egg bootstrap problems.

No need for a special out of memory function -- it's just a kind of
fatal error. Also make fatal_error() call dump_memory_layout() for
easier debugging.

VM: fix move_file called from save_image
...
save_image() shouldn't throw exceptions because if the 'then_die'
argument is t it would leave factor in an inconsistent state. So
therefore move_file() should be fixed and raw_fclose() called instead of
safe_fclose().

VM: always use undecorated names when loading ffi functions
...
For win32, Factor tries four different function names when loading
stdcall and fastcall functions, in case decorated names are used in the
dll. It seems to not be necessary because a dll meant for 3rd party use
will always export undecorated
names (http://blogs.msdn.com/b/oldnewthing/archive/2004/01/12/57833.aspx ).

The address to the win32 relocation handler can be stored in a special

type.

VM: fix jit-signal-handler-prolog/epilog to account for the home space
...
Windows 64bit abi requires callers to reserve 32 bytes of home space in
the stack frame which the callee is free to clobber. Previous versions
of VS didn't compile code to take advantage of the home space so it
worked fined. VS2015 however, is using the home space which causes
registers and flags that were supposed to be saved to be
overwritten. The fix is to put a little extra empty space at the bottom
of the stack frame.
