look, you even seem to have a good guess what to fix XD
can you please do it?:P
I officially blame reaVer for this commit.

rec:
--A couple of workarounds, as I don't plan to fix these bugs on rec_v1x
pvr:
--Other workarounds

This commit fixes crashes, and some known dynarec glitches, by either doing
printf() instead of die or simply avoiding the codepath. This has a small
performance penalty. You can revert to the old behavior by disabling "Accurate
Mode" on the gui (or using nullDC:Dynarec.SafeMode=0). Accurate mode is by
default enabled.

Prolly i forgot some known bugs, if i remember more o them will include them on
later commits.

Fixes Issue 256 .
Hackfixes Issue 120. (pvr related)
Issues 257, 219, 258, 261, 267 and 291 should be re-tested with this rev.
