Translate GEP instructions on structs to GEP on int8* 

http://b/24142721

X86 data layout has 64-bit scalars aligned at 4-byte boundaries, while
ARM aligns these data at 8-byte boundaries.  To bring frontend- and
backend-generated code into agreement, this patch adds a pass to
translate GEPs on structs to GEPs with int8* operands and byte offsets.
This pass runs only on X86 targets.
