x86: unify desc_struct
This patch aims to make the access of struct desc_struct variables equal across architectures. In this patch, I unify the i386 and x86_64 versions under an anonymous union, keeping the way they are accessed untouched (a and b for 32-bit code, individual bit-fields for 64-bit). This solution is not beautiful, but will allow us to integrate common code that differed by the way descriptors were used. This is to be viewed incrementally. There's simply too much code to be fixed at once. In the future, goal is to set up in a single way of acessing the desc_struct fields.
