qemu-e2k/target/tricore/translate.c
Bastian Koppelmann a21993c7f9 target/tricore: Fix OPC2_32_RRPW_EXTR for width=0 
if width was 0 we would run into the assertion:

qemu-system-tricore: tcg/tcg-op.c:217: tcg_gen_sari_i32: Assertion `arg2 >= 0 && arg2 < 32' failed.o

The instruction manual specifies undefined behaviour for this case. So
we bring this in line with the golden Infineon simlator 'tsim', which
simply writes 0 to the result in case of width=0.
