Hi Igor,
Here is one of the changes for vector ics. This infrastructure is only
utilized
when the vector_ics flag is on, with some careful guard/default values when
it's
off. PTAL, thx!

Description:
A type vector with multiple IC types needs metadata.
This CL adds a bitset to describe the type of IC in each IC slot.
This is necessary for clearing ICs of different types.
With FLAG_vector_ics off (the current state), it's not required because
CALL_IC is the only type of IC in the vector.
