Hi,

This series fixes EXECUTing relative branches: currently the offset is
incorrectly applied to EXECUTE and not the branch itself. This is
similar to what I previously fixed for load/store instructions.

Unfortunately here it's not feaisble to use the ri2 field, since it
would break the direct branch optimization. Instead, introduce the
disas_jdest() macro and pass its output to help_branch().

Patch 1 is the fix, patch 2 is the test.

Best regards,
Ilya
