Howdy,
Correctness wins over performance every time, so I am +1 for this
branch to merge.

We took a small hit for the indirection NCI caused. We're not doing
that anymore, so it should be a little faster.

Howdy,
Peter, can you comment on the possible performance-related changes
that this branch could cause?
Have you done any benchmarks?

The pmc2c-multi-nativepccmethod branch changes the implementation of
MULTIs in .pmc files from NCI to NativePCCMethod. This means that
these now handle their own PCC, in stead of rellying on NCI thunks to
accomplish this. These can now be modified to access a more broad
range of PCC functionality.
