x86: make a20_mask int32_t

This makes the savevm code correct, and sign extensins gives us exactly
what we need (namely, sign extend to 64 bits when used with 64bit addresess.

Once there, change 0x100000 for 1 << 20, that maks all a20 use the same syntax....

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

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)....

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...

Get rid of _t suffix

Some not so obvious bits, slirp and Xen were left alone for the time
being.

x86: use globals for CPU registers

Use globals for the 8 or 16 CPU registers on i386 and x86_64.
