Ryan Houdek ff1d51c7bd FEXCore: Fix-up edge case behaviour on faulting instructions ...

x86 has six instructions that will fault on us that we mostly handled. A
few of these weren't being handled correctly.

One problem is that RIP needs to synchronize differently depending on
which fault instruction it is. Some instructions fault at the
instruction RIP, some at the instruction afterwards.

Additionally some of the metadata generated around the signal delegation
wasn't correct.

With behaviour of all of these instructions changed, it will now be
easier to switch over to non-faulting guest synchronous signals off of
these instructions. This doesn't go far enough to change that behaviour
yet.

I noticed this when looking at Elden Ring's weird faulting behaviour
with ud2 and `int 0x2d`. This made me investigate since I had a
suspicion that we weren't handling both cases correctly.

With this change, Elden Ring is now stabilized and works under FEX.
