  • Wrapped tick() in Try/Catch to dump CPU state in the event of an exception to help with debugging
  • Added support for both SS & DS as destination segments for FISTP
  • Additional FISTP Unit Tests

dude!

- `FISTP` on i386/i486 only supports 32-bit Integers, updated code when decompiler incorrectly identifies a 64-bit operation
- Added Casting & Conversion Checks setting proper FPU flags on failure

Looks like the checks are failing?

- Handle Logger in Unit Tests (null)
- Set CPU ControlWord properly if value from the FPU is larger than a signed 32-bit Integer
