KVM: x86 emulator: Fix stack instructions on 64-bit mode

Browse source

Stack instructions are always 64-bit on 64-bit mode; many of the
emulated stack instructions did not take that into account.  Fix by
adding a 'Stack' bitflag and setting the operand size appropriately
during the decode stage (except for 'push r/m', which is in a group
with a few other instructions, so it gets its own treatment).

This fixes random crashes on Vista x64.
