[v2,0/6] TriCore PCXI/ICR register fixes

Message

Hi,

the main motivator for this series was
https://gitlab.com/qemu-project/qemu/-/issues/1453. To test that I'm not
screwing up this refactor I also extended the tests by C programs so we can test
the PCXI/ICR registers by recursive function call. Through these tests I also
found a problem, where we were not correctly updating PSW when we did a context
save.

Cheers,
Bastian

v1 -> v2:
    - Created icr_ie_mask for DisasCtx to simplify SYS_ENABLE and SYS_DISABLE
      insns translation.
