[PATCH 4/4] Activate JIT code unwinder for i386.

[Sanjoy Das <sanjoy@playingwithpointers.com>]

Registers the (pseudo) unwinder for JIT code for i386. This can probably be expanded to other architectures after some testing and review.

gdb/ChangeLog:
	* i386-tdep.c: Activate JIT unwinder for i386.
