X86: Fix kernel Input/Output GetElementPtr offset issue
http://b/24142721
The disagreement between module and x86 target datalayout causes
mismatched size calculation of structs with 64-bit scalar fields.
This patch solves the issue by treating input and output pointers as
byte* pointers, indexing them with explicit byte offsets computed using
a modified data layout for x86, with alignment for 64-bit scalars set to
8-bytes, and casting the indexed pointers back to the real type.
