x86/cpuid: move CPUID functions into separate file

about half of target-i386/helper.c consist of CPUID related functions.
Only one of them is a real TCG helper function. So move the whole
CPUID stuff out of this into a separate file to get better
maintainable parts....

x86/cpuid: replace magic number with named constant

CPUID leaf Fn8000_0001.EDX contains a copy of many Fn0000_0001.EDX bits.
Define a name for this mask to improve readability and avoid typos.

Remove cpu_get_phys_page_debug from userspace emulation

cpu_get_phys_page_debug makes no sense for userspace emulation, so remove it.

Move TARGET_PHYS_ADDR_SPACE_BITS to target-*/cpu.h.

Removes a set of ifdefs from exec.c.

Introduce TARGET_VIRT_ADDR_SPACE_BITS for all targets other
than Alpha. This will be used for page_find_alloc, which is
supposed to be using virtual addresses in the first place....

target-i386: fix SIB decoding with index = 4

A SIB byte with an index of 4 means "no scaled index", even if the scale
value is not 0. In 64-bit mode, if REX.X is used, an index of 4 selects
%r12. This is correctly handled by the computation of the index variable,...

KVM: x86: Restrict writeback of VCPU state

Do not write nmi_pending, sipi_vector, and mpstate unless we at least go
through a reset. And TSC as well as KVM wallclocks should only be
written on full sync, otherwise we risk to drop some time on state
read-modify-write....

KVM: Rework VCPU state writeback API

This grand cleanup drops all reset and vmsave/load related
synchronization points in favor of four(!) generic hooks:

- cpu_synchronize_all_states in qemu_savevm_state_complete
(initial sync from kernel before vmsave)...
