[PATCH] Add test for i386 prologue analyzer

[Mark Kettenis <kettenis at chello dot nl>]

Folks,

I added a testcase for gdb/1253.  I'll probably add more i386-related
prologue analyzer cases here.

I checked this in on mainline.  Andrew, do you want this on the branch
too?  If so I'll move if the test proves to be robust on mainline.

Mark
