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 ).

VM: get rid of the odd RT_EXCEPTION_HANDLER relocation
...
The address to the win32 relocation handler can be stored in a special
object and be accessed by jit-install-seh. Doing it that way is better
because you can remove a lot of special code related to that relocation
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.

VM: bump stack_reserved from 1kb to 4kb

The added test case fails with a doulbe fault, which appears to be
caused by a stack overflow in the code that tries to handle the stack
overflow. So bumping it to 4096 bytes should give the code enough stack
space to play with.
