17 Refactor: interrupts made 100% compatible to original:
IRQ priority logic implemented as in original MCS51.
Register IP implemented.
Interrupt mini-testbench code updated accordingly.		 ja_rd 4132d 20h /light52/
16 Test bench modified: now tests IRAM and SFR addresses when testing direct mode instructions (instead of only IRAM). ja_rd 4134d 17h /light52/
15 Test bench modified: now tests IRAM and SFR addresses when testing direct mode instructions (instead of only IRAM). ja_rd 4138d 14h /light52/
14 BUG FIX: <DJNZ dir, rel> didn't work when addressing an SFR.
Signal direct_addressing fixed.		 ja_rd 4138d 20h /light52/
13 BUG FIX: <DJNZ dir, rel> was tested only with IRAM addresses.
Now it's tested with an SFR too.
The test package has been fixed too with a XRAM configuration suitable for the test bench (it was zero).		 ja_rd 4138d 20h /light52/
12 BUG FIX: The build script did not configure XDATA space properly.
XDATA size was zero, which made the HW tests fail.		 ja_rd 4138d 23h /light52/
