perf intel-pt: Split VM-Entry and VM-Exit branches
Events record a single cpumode so the tools cannot handle a branch from
the host machine to a virtual machine, or vice versa. Split it in two so
that each branch can have a different cpumode.
E.g. host ip -> guest ip
becomes: host ip -> 0
0 -> guest ip
