x86: Extend XSAVE support to unbound state
* i386/i386/fpu.c (fp_xsave_size): New variable.
(init_fpu): Save XSAVE size to fp_xsave_size.
(fpu_module_init): Pass fp_xsave_size as size to kmem_cache_init.
(fpu_set_state, fp_load, fp_state_alloc): Use fp_xsave_size to clear
ifps.
* i386/include/mach/i386/fp_reg.h (struct i386_xfp_save): Replace static
fp_yreg_word with extended field.
* i386/i386/thread.h (struct i386_fpsave_state): Make fp_valid field
first in the structure to let the extended finish the structure.
