target-i386: Fix exceptions for fxsave/fxrstor

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...

target-i386: add RDTSCP support

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()...

target-i386: add SSE4a instruction support

target-i386: add lock mov cr0 = cr8

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:ECX1).

Revert "Get rid of _t suffix"

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...
