[WinEH] Put finally pointers in the handler scope table field

[WinEH] Put finally pointers in the handler scope table field

We were putting them in the filter field, which is correct for 64-bit
but wrong for 32-bit.

Also switch the order of scope table entry emission so outermost entries
are emitted first, and fix an obvious state assignment bug.
