The real i386_thread_state Mach structure has an alignment of 8 on x86_64. However, in struct sigcontext, the compiler was packing sc_gs (which is the first member of sc_i386_thread_state) into the same 8-byte slot as sc_error; this resulted in the rest of sc_i386_thread_state members having wrong offsets relative to each other, and the overall sc_i386_thread_state layout mismatching that of i386_thread_state. Fix this by explicitly adding the required padding members, and statically asserting that this results in the desired alignment. The same goes for sc_i386_float_state. Checked on x86_64-gnu.
