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.
