[sh4] Refactor jumps in baseline JIT to return label after the jump.
https://bugs.webkit.org/show_bug.cgi?id=123734
Patch by Julien Brianceau <jbriance@cisco.com> on 2013-11-04
Reviewed by Michael Saboff.
Current implementation of jumps in sh4 baseline JIT returns a label on the jump itself
and not after it. This is not correct and leads to issues like infinite loop the DFG
(https://bugs.webkit.org/show_bug.cgi?id=122597 for instance). This refactor fixes this
and also simplifies the link and relink procedures for sh4 jumps.
