This reverts commit 3031efab.

This patch corrects the following aspects of exception generation in
fxsave/fxrstor:

* Generate #GP if the operand is not aligned to a 16 byte boundary
* Generate #UD if the LOCK prefix is used
* For CR0.EM = 1 #NM is generated, not #UD

The new devices added here are still not functional -
partially because some patches are still missing,
partially because I cannot test them. Nevertheless
they belong to the same family and will be supported
by this driver some day.

As soon as they work, they will also be added to hw/pci.c.

A lot of entries are unused (they were added by copy + paste
from other drivers during development of eepro100.c).

Removing them from nic_save, nic_load makes any
old saved status incompatible, so a new version
for the virtual machine data was needed, too.

RDTSCP reads the time stamp counter and atomically also the content
of a 32-bit MSR, which can be freely set by the OS. This allows CPU
local data to be queried by userspace.
Linux uses this to allow a fast implementation of the getcpu()
syscall, which uses the vsyscall page to avoid a context switch.
AMD CPUs since K8RevF and Intel CPUs since Nehalem support this
instruction.
RDTSCP is guarded by the RDTSCP CPUID bit (Fn8000_0001:EDX[27]).

This adds support for the AMD Phenom/Barcelona's SSE4a instructions.
Those include insertq and extrq, which are doing shift and mask on
XMM registers, in two versions (immediate shift/length values and
stored in another XMM register).
Additionally it implements movntss, movntsd, which are scalar
non-temporal stores (avoiding cache trashing). These are implemented
as normal stores, though.
SSE4a is guarded by the SSE4A CPUID bit (Fn8000_0001:ECX[6]).

AMD CPUs featuring a shortcut to access CR8 even from 32-bit mode.
If you use the LOCK prefix with "mov CR0", it accesses CR8 instead.
This behavior is guarded by the CR8_LEGACY CPUID bit
(Fn8000_0001:ECX[1]).

Currently zero extensions ops are implemented by a and op with a
constant. This is then catched in some backend, and replaced by
a zero extension instruction. While this works well on RISC
machines, this adds a useless register move on non-RISC machines.

Example on x86:
  ext16u_i32 r1, r2
is translated into
  mov    %eax,%ebx
  movzwl %bx, %ebx
while the optimized version should be:
  movzwl %ax, %ebx

This patch adds ext{8,16,32}u_i{32,64} TCG ops that can be
implemented in the backends to avoid emitting useless register
moves.

Make an "#if 0"'d printf() in load_elf_binary(), probably left to aid in
debugging, reflect what the actual code does. The current printf() will
only confuse those who "#if 1" it (it certainly confused me enough to
write this trivial patch).

Looks like linux-user code was correct, just unreadable: what it wanted
to do with "-=" was really assign a negative number, not decrement.  Fix

Additional argument (whether to try poll mode) is only passed with
VOICE_ENABLE command.

Thanks to Markus Armbruster for noticing the potential breakage.

In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem.  Something
like this _must_ be presented on the list first so people can provide input
and cope with it.
