target-i386: fix segment limit check in ljmp 
The current implementation has three bugs,
* segment limits are not enforced in protected mode if the L bit is set
in the target segment descriptor
* segment limits are not enforced in compatibility mode (ljmp to 32-bit
code segment in long mode)
* #GP(new_cs) is generated rather than #GP(0)

Now the segment limits are enforced if we're not in long mode OR the
target code segment doesn't have the L bit set.

Backports commit db7196db5d5d932f388643baae6835f8dcda6921 from qemu
