Not that I'm aware.  Some of the infrastructure is already there.
See `Source/cmState.h`.  When first added it supported capturing
a snapshot of the state before every function call and at other
key points.  However, we had to remove some of that because it
led to unbounded memory accumulation.  If it were to be added as
a debugging mode that may be okay, but it would likely have to
do something besides keeping everything in memory.
