2023-10-03target/tricore: Fix RCPW/RRPW_INSERT insns for width = 0Bastian Koppelmann
we would crash if width was 0 for these insns, as tcg_gen_deposit() is undefined for that case. For TriCore, width = 0 is a mov from the src reg to the dst reg, so we special case this here.

2023-06-21target/tricore: Honour privilege changes on PSW writeBastian Koppelmann
the CPU can change the privilege level by writing the corresponding bits in PSW. If this happens all instructions after this 'mtcr' in the TB are translated with the wrong privilege level. So we have to exit to the cpu_loop() and start translating again with the new privilege level.
