SuperPMI collection fix by instantiating 'GetExactClasses' if it is null

[TIHan]

SuperPMI collections have been failing since yesterday. Upon investigation, I was able to reproduce the issue simply by trying to SuperPMI collect a hello world app.

There was a null variable, GetExactClasses, trying to be accessed. It was added in #64497. The fix is to initialize this variable if it is null. Looking at similar variables like this, the same logic exists, for example:

if (GetArgType == nullptr)
GetArgType = new LightWeightMap<Agnostic_GetArgType_Key, Agnostic_GetArgType_Value>();

I think repGetExactClasses is also missing an AssertMapAndKeyExist.

Would be nice to get this fixed soon.

I am seeing this failing in superpmi-replay. I will send out a PR shortly.
