RooKeysPdf: faster initialisation of the lookup table

The construction of a RooKeysPdf is now much faster for large data sets.
This is achieved by carefully analysing where the different Gaussians
that the code superimposes can actually contribute. If a contribution
is smaller than the machine precision, the code stops trying to put in
those contributions (it would be lost in rounding anyway), which leads
to roughly 40 % faster construction of the class for large data sets.
fix commit 127aa29aee7bbf41be3b495821283ea7403af582 which prevents delete under certain circumstances
Comment out a potentially useless check...
Fix for ROOT-6194 and ROOT-6164
Improve performance with early return.

When the TClass is found directly in the list, return early
to avoid the costly parsing of the class name.  This improve
performance in general and reduce lock contention (the lock
is released faster) in multi-thread environment.
