MCE: Fix bug of IA32_MCG_STATUS after system reset

Now, if we inject a fatal MCE into guest OS, for example Linux, Linux
will go panic and then reboot. But if we inject another MCE now,
system will reset directly instead of go panic firstly, because
MCG_STATUS.MCIP is set to 1 and not cleared after reboot. This is does...

remove pending exception on vcpu reset.

Without this qemu can even start on kvm modules with events support
since default value of exception_injected in zero and this is #DE

target-i386: Fix "call im" on x86_64 when executing 32-bit code

Similarly to what is done in 32938e127f50a40844a0fb9c5abb8691aeeccf7e
for "jmp im", trunc the immediate to 32-bit when not running in 64-bit
mode.

Revert "kvm: x86: Save/restore exception_index"

This reverts commit ebbc8a3d8e76d0402f8a08c10c0f32e24715d41d.

As suggested by Jan Kiszka,

"It was obsoleted by d1793b836f8f123b961c613de1bb1c0c185c84cc and now
   saves/restores a useless field."

kvm: x86: Use separate exception_injected CPUState field

Marcelo correctly remarked that there are usage conflicts between QEMU
core code and KVM /wrt exception_index. So spend a separate field and
also save/restore it properly.

target-i386: Update CPUID feature set for TCG

The CPUID features QEMU presented to the guest were not up-to-date
with QEMU's emulated feature set.
Add the missing bits of recent (and not so recent) additions to
QEMU's emulation engine.
For stability reasons only the user mode usable bits are exposed for...
