x86/headers: Unify 'struct _fpstate_ia32' and i386 struct _fpstate
'struct _fpstate_ia32' and 'struct _fpstate' on i386 are
identical in all fields, except 'padding1' being named
'padding'.
We unify the two structures and add a union that is both named
'padding1' and 'padding', in the (unlikely) case there's
user-space code that relies on the padding field name.
We rename the two main types to be:
struct _fpstate_32
struct _fpstate_64
for the 32-bit and 64-bit frame, and map them to the main and
compat structure names (_fpstate) depending on whether we are on
32-bit or on 64-bit kernels.
We also keep the old _fpstate_ia32 name as a legacy name.
