x86/xenoprof: fix 32-bit guest stack handling after c/s 24537:3c0a533d3af0

32-bit guests don't have 64-bit precudrure return addresses - both
elements of struct frame_head_32bit should be 32 bits wide, not just
the frame link pointer.

Further, consolidate the whole handling here (also in the native size
guest case) to properly use guest handles and guest memory accessors.
