[hatari-devel] WinUAE cpu core updated to 3.4 b4

[Nicolas Pomarède <npomarede@xxxxxxxxxxxx>]

Hi

I just pushed some updates to the WinUAE cpu core included in Hatari to 
sync with the latest version 3.4 b4.

Most of the changes related to Hatari were about the better prefetch for 
68020/03 branch instructions, but thoses changes were in fact already 
pushed to Hatari some months ago when discussing them with Toni.

The other changes are mostly some files reordering to use a directory 
structure closer to the one used in WinUAE's sources, as well as 
cleaning our own "compat.h", by using instead some files that were 
introduced after WinUAE 3.1 to get a better OS independant interface 
(those changes were often provided by FS-UAE author Frode Solheim).

Apart from that, a few fixes are available for some rare cases which 
were not reported/used in Hatari (unimplemented opcodes, M bit), so 
there should not be any visible change for us.

As WinUAE's sources changed a lot since 3.1, this will be mostly useful 
to easily merge further changes.

Falcon / TT modes are still working in my quick tests, let me know if 
you see some regressions.
