dd4f5d2437 Implement xsetbv(), xsave() and xrstor() providing C access to the 
similarly named CPU instructions.

Since our in-tree binutils gas is not aware of the instructions, and
I have to use the byte-sequence to encode them, hardcode the r/m operand
as (%rdi). This way, first argument of the pseudo-function is already
placed into proper register.

292177e67a Improve abstraction. Eliminate direct access by elf*_load_section() 
to an OBJT_VNODE-specific field of the vm object.  The same
information can be just as easily obtained from the struct vattr that
is in struct image_params if the latter is passed to
elf*_load_section().  Moreover, by replacing the vmspace and vm
object parameters to elf*_load_section() with a struct image_params
parameter, we actually reduce the size of the object code.

builtins, rather than the __asm hack.  Somehow I missed the existence of this

    o  a trap is set on EXIT
    o  a function returns 1 and causes the script to abort
